In the late summer of August 2025, the war in Ukraine grinds on, a brutal fixture in the global landscape. What began over a decade earlier in 2014 as a simmering conflict in the country's eastern Donbas region and the annexation of Crimea had, on February 24, 2022, exploded into the largest and most destructive conventional war in Europe since the Second World War. This book is an attempt to chronicle that explosion and its turbulent, violent aftermath—a story of invasion and resistance, of geopolitical realignment, and of immense human suffering that, as of this writing, has no clear end in sight. The conflict has become a sprawling, multifaceted struggle, reshaping not only the two primary belligerents but also the very tenets of international order.

The road to full-scale war was a long and complex one, paved with centuries of intertwined and often fraught history between Russia and Ukraine. Their shared origins in Kievan Rus' gave way to centuries of divergence, with Ukraine developing its own distinct language, culture, and national identity while frequently falling under the dominion of powerful neighbors, including the Russian Empire and later the Soviet Union. The collapse of the USSR in 1991 marked a pivotal moment, granting Ukraine the independence its people had overwhelmingly voted for. The subsequent decades were marked by a delicate balancing act, as Ukraine navigated its sovereignty while Russia sought to maintain its influence, a dynamic that would ultimately prove unsustainable.

The events of 2014 served as a violent prelude to the wider conflict. Following Ukraine's pro-Western Revolution of Dignity, which ousted a Kremlin-friendly president, Russia responded by annexing the Crimean Peninsula and backing a separatist insurgency in the eastern regions of Donetsk and Luhansk. The ensuing eight-year war in the Donbas claimed over 14,000 lives and became a grim, localized foreshadowing of the devastation to come. It was a period of undeclared hostilities, cyber warfare, and failed diplomatic efforts, all while a massive Russian military buildup began to take shape along Ukraine's borders in 2021, setting the stage for a dramatic escalation.

When Russian forces crossed the border on February 24, 2022, the stated goals were the "demilitarization and denazification" of Ukraine. The initial Russian strategy appeared to bank on a swift, decisive victory—a "blitzkrieg" aimed at capturing the capital, Kyiv, within days and decapitating the Ukrainian government. Many international observers shared this assessment, predicting a rapid collapse of Ukrainian resistance in the face of Russia's seemingly overwhelming military might. What transpired, however, confounded those expectations and set the course for a protracted and bloody struggle that continues to this day.

The initial phase of the invasion was marked by fierce and unexpectedly effective Ukrainian resistance. The planned lightning strike on Kyiv faltered amidst logistical failures, determined defense, and the resolve of a civilian population that mobilized to support its armed forces. By April 2022, Russian troops had withdrawn from northern Ukraine, leaving behind a trail of devastation and evidence of widespread atrocities, most infamously in the town of Bucha. This early failure forced a strategic pivot from Moscow, which then concentrated its efforts on securing the Donbas and a land corridor along the southern coast.

This shift initiated a new and grinding phase of the war, characterized by brutal battles of attrition for key cities and territories. The siege of Mariupol, culminating in the heroic last stand at the Azovstal steel plant, became a symbol of both Ukrainian defiance and the war's staggering human cost. The conflict's momentum would continue to shift, with Ukraine launching successful counteroffensives in the Kharkiv and Kherson regions in late 2022, demonstrating its capacity to reclaim occupied territory and forcing Russian retreats. These victories, however, were followed by a grueling and costly struggle for the eastern city of Bakhmut, which devolved into a meat grinder for both sides.

By 2023, the conflict had largely settled into a war of attrition. Ukraine's much-anticipated summer counteroffensive, aimed at breaking through heavily fortified Russian lines in the south, made limited gains in the face of dense minefields and stiff resistance. The front lines, stretching for hundreds of miles, became a landscape of trench warfare, artillery duels, and relentless drone activity, reminiscent of the static battles of the First World War but infused with twenty-first-century technology. The year 2024 saw this stalemate deepen, with both sides engaged in a relentless struggle for incremental gains at a tremendous cost in lives and equipment.

This war has not been confined to the trenches. It has been fought intensely in the air, with Russian missile and drone strikes targeting Ukrainian cities and critical infrastructure, and Ukrainian drones striking deep into Russian territory. It has been fought at sea, where Ukrainian naval drones have remarkably challenged the dominance of the Russian Black Sea Fleet, sinking or damaging a significant portion of it and helping to reopen vital grain export corridors. And it has been waged on the economic front, with an unprecedented regime of international sanctions imposed on Russia and a global coalition providing vast sums of military and financial aid to Ukraine.

The impact of the war has rippled across the globe, triggering crises in energy and food security, exacerbating inflation, and redrawing geopolitical alliances. It has prompted a historic expansion of NATO, with Finland and Sweden joining the alliance, and has forced a fundamental reassessment of European security architecture. The conflict has also become a laboratory for modern warfare, demonstrating the transformative role of drones, artificial intelligence, and open-source intelligence on the battlefield, offering lessons that military establishments worldwide are studying with urgency.

This book aims to provide a comprehensive account of this ongoing conflict. It will delve into the historical roots of the animosity, examine the critical turning points from the Maidan Revolution to the full-scale invasion, and provide detailed chronicles of the major military campaigns that have defined the war. Beyond the battlefield, it will explore the international response, the punishing economic warfare, the societal transformations within both Ukraine and Russia, and the profound human cost of the violence—the millions displaced, the cities destroyed, and the lives irrevocably shattered.

Writing the history of a war as it is still being fought is an inherently challenging task. The fog of war is thick with propaganda, misinformation, and the raw emotions of ongoing trauma. casualty figures are contested, and the full picture of many events will only emerge with time. This volume is, therefore, a first draft of history, a chronicle of the war as understood in August 2025. It is an effort to document, in a clear and factual manner, the events that have led to this moment and to provide a foundational understanding of a conflict that has already defined a decade and will undoubtedly shape the world for many years to come.

To understand the war that erupted in the third decade of the 21st century, one must first rewind the clock over a millennium. The story of both Ukraine and Russia begins in the vast medieval state of Kievan Rus'. Centered in Kyiv, this federation of East Slavic tribes flourished from the 9th to the mid-13th century, becoming a powerful and sophisticated entity in Eastern Europe. For both modern nations, this period is a foundational pillar of their national identity, a shared baptismal font. It was here, under the reign of Volodymyr the Great in 988, that the people of Rus' adopted Orthodox Christianity from Byzantium, a moment that would profoundly shape the cultural, spiritual, and political trajectory of the entire region for centuries to come.

This shared cradle of civilization, however, does not tell a simple story of unified origin. Russian historiography, particularly that promoted by the state, has often depicted Kievan Rus' as the direct, linear ancestor of the Muscovite state and later the Russian Empire, portraying Ukrainians ("Little Russians") and Belarusians ("White Russians") as junior branches of a single "All-Russian" people. Ukrainian national identity, conversely, posits a direct line of succession from Kievan Rus' to modern Ukraine, arguing that Moscow's rise was a separate, more autocratic development in the northeastern periphery, while Ukrainian lands maintained and developed the direct cultural and legal heritage of Kyiv.

The unity of Kievan Rus' was irrevocably shattered in the mid-13th century by the Mongol invasion. The sack of Kyiv in 1240 was a cataclysmic event that sent the different principalities of Rus' spinning into separate orbits. The western and southern lands, the core of modern-day Ukraine, gradually fell under the influence and later the direct rule of the Grand Duchy of Lithuania. This period marked a profound divergence. While the northeastern principalities, centered around Moscow, languished under the "Tatar Yoke," developing a centralized, autocratic political system, the Ukrainian lands experienced a very different evolution.

Within the Grand Duchy of Lithuania, and later the Polish-Lithuanian Commonwealth which was formed by the Union of Lublin in 1569, Ukrainian society was exposed to the currents of European legal and political thought, including the Magdeburg Law for city governance and the ideals of a noble republic. This period saw the flourishing of a distinct Ruthenian (the precursor to modern Ukrainian and Belarusian) identity and language. While the nobility increasingly adopted Polish culture and the Catholic faith, the majority of the populace remained Orthodox, creating simmering social and religious tensions that would define the coming centuries.

Out of this crucible of foreign rule and religious strife emerged the Zaporozhian Cossacks. Originally free frontiersmen who defended the southern steppes against Tatar raids, the Cossacks developed into a formidable military and political force. They became the fierce defenders of Orthodox Christianity and Ruthenian identity against Polish domination. This simmering conflict exploded in 1648 with the Khmelnytsky Uprising, a massive Cossack-led rebellion against the Polish-Lithuanian Commonwealth that convulsed the region and is seen in Ukrainian history as a war of national liberation.

Seeking allies in his protracted struggle, the Cossack leader, Hetman Bohdan Khmelnytsky, made a fateful decision. In 1654, at the council of Pereiaslav, he sought the protection of the Muscovite Tsar, Alexei I. The resulting Treaty of Pereiaslav is one of the most contentious and differently interpreted events in Eastern European history. For Moscow, and later Russian imperial and Soviet historiography, this was the moment of "reunification" of the Russian peoples. For many Ukrainians, it was a temporary military alliance born of desperation, a pact between sovereigns that was meant to preserve Cossack autonomy but was instead twisted by Moscow into a pretext for absorption and domination.

What began as a protectorate rapidly devolved into subjugation. Over the next century, Moscow systematically dismantled the autonomy of the Cossack Hetmanate. Catherine the Great, an empress not known for her tolerance of regional exceptions, finished the job. In 1764, she abolished the office of the Hetman, and in 1775, she ordered the destruction of the Zaporozhian Sich, the Cossack stronghold, fully integrating the Ukrainian lands into the Russian Empire. With political autonomy extinguished, a concerted policy of Russification began.

Throughout the 19th century, the Tsarist government actively suppressed the burgeoning Ukrainian national movement. The Ukrainian language was dismissed as a "Little Russian dialect," a peasant patois unfit for high culture or education. This policy was codified in official decrees. The Valuev Circular of 1863 banned the publication of most Ukrainian-language books, stating that a separate Ukrainian language "never existed, does not exist, and cannot exist." This was followed by the even more restrictive Ems Ukaz in 1876, signed by Tsar Alexander II, which forbade all Ukrainian-language publications, stage performances, and even the import of Ukrainian books from abroad.

Despite this intense pressure, a Ukrainian national consciousness continued to grow. Poets and writers, most notably the national bard Taras Shevchenko, nurtured the language and articulated a vision of a distinct Ukrainian identity rooted in its Cossack past and separate destiny. The cultural and intellectual revival of the 19th century laid the groundwork for the political aspirations of the 20th. The collapse of the Russian Empire in 1917 provided an opportunity. In the chaos of revolution and civil war, Ukrainian leaders declared the creation of the Ukrainian People's Republic (UPR).

This brief, chaotic period of independence from 1917 to 1921 was a desperate struggle for survival. Beset on all sides by Bolsheviks, White Russians, Poles, and internal factions, the UPR ultimately fell. By 1922, the majority of Ukrainian territory had been forcibly incorporated into the new Union of Soviet Socialist Republics (USSR). While the Bolsheviks initially promoted a policy of "Ukrainization" in the 1920s to shore up their support, this thaw was short-lived and brutally reversed by Joseph Stalin.

In the early 1930s, Stalin unleashed a campaign of terror upon Ukraine that would forever scar the nation's soul. As part of his drive to collectivize agriculture and crush all vestiges of Ukrainian nationalism, the Soviet regime engineered a devastating man-made famine known as the Holodomor, or "death by hunger." Impossible grain quotas were imposed on Ukrainian villages, and authorities confiscated all available food. The borders of Ukraine were sealed to prevent starving peasants from seeking refuge. It is estimated that between 3.5 and 5 million Ukrainians perished from starvation between 1932 and 1933. This act is widely considered by many nations and historians to be a genocide, a deliberate attempt to destroy the Ukrainian peasantry as the backbone of the nation.

The Second World War brought further devastation, as Ukraine became a primary battlefield between Nazi Germany and the Soviet Union. The conflict was complex, with some Ukrainians initially seeing the Germans as liberators from Soviet tyranny, while others fought heroically in the ranks of the Red Army. Ukrainian nationalist partisans, notably the Ukrainian Insurgent Army (UPA), fought against both the Nazis and the Soviets, continuing their insurgency well into the 1950s. After the war, the borders of the Ukrainian Soviet Socialist Republic were finalized, incorporating western territories that had previously been part of Poland.

A curious footnote of the Soviet era occurred in 1954, when Soviet leader Nikita Khrushchev, in a move ostensibly to celebrate the 300th anniversary of the Treaty of Pereiaslav, oversaw the transfer of the Crimean Peninsula from the Russian SFSR to the Ukrainian SSR. The official rationale cited the "integral character of the economy, the territorial proximity and the close economic and cultural ties" between Crimea and Ukraine. At the time, within the monolithic structure of the USSR, this administrative change was largely symbolic. Decades later, however, after the collapse of the Soviet Union, it would become a major point of contention.

The final decades of the Soviet Union saw a continuation of Russification policies, albeit less overtly brutal than under Stalin. Russian was promoted as the language of "interethnic communication," and its knowledge was essential for social and professional advancement, marginalizing the Ukrainian language in public life, education, and media. Yet, the national identity, forged through centuries of struggle and preserved through language, culture, and a deep-seated historical memory of independence, endured.

The Chernobyl nuclear disaster in 1986, a catastrophe that Moscow initially tried to cover up, exposed the Kremlin's disregard for Ukrainian lives and fueled widespread public discontent. As Mikhail Gorbachev's policies of glasnost and perestroika loosened the state's iron grip, national movements across the Soviet republics surged. In Ukraine, the Rukh (People's Movement of Ukraine) led the charge for sovereignty.

The final, decisive moment came in the wake of the failed hardline coup in Moscow in August 1991. On August 24, 1991, the Ukrainian parliament declared the country's independence. This declaration was put to a national referendum on December 1, 1991. The result was an overwhelming affirmation of sovereignty. Over 92 percent of voters, with majorities in every region of the country—including Crimea—voted "Yes" to independence. The centuries-long entanglement with Moscow was, it seemed, finally over.

The first decade of independence, however, was fraught with challenges. The transition from a communist command economy to a market-based system was painful, marked by hyperinflation and economic hardship. Politically, the young state had to navigate its relationship with a Russia that was struggling to accept its diminished imperial status. Several critical issues immediately created tension.

The first was the fate of the vast Soviet nuclear arsenal stationed on Ukrainian territory. At its independence, Ukraine inherited the world's third-largest nuclear stockpile, a legacy that made it an instant major player on the global security stage. After protracted negotiations, Kyiv agreed to relinquish these weapons in exchange for security assurances from the United States, the United Kingdom, and, crucially, Russia. These assurances were formalized in the 1994 Budapest Memorandum, in which the signatories pledged to respect Ukraine's independence, sovereignty, and existing borders.

Another major point of friction was the division of the Soviet Black Sea Fleet, headquartered in the Crimean port of Sevastopol. The dispute was laden with emotion and symbolism. For many Russians, Sevastopol was a "city of Russian glory," and the idea of it belonging to another country was difficult to stomach. After years of tense negotiations, the fleet was finally divided in 1997, and Ukraine agreed to lease naval bases in Sevastopol to Russia. The agreement was part of a broader Treaty of Friendship, Cooperation, and Partnership, in which Russia once again formally recognized Ukraine's borders, including Crimea.

Throughout the 1990s and early 2000s, Ukraine pursued what its leaders termed a "multi-vector foreign policy." This was a delicate balancing act, an attempt to cultivate closer ties with the West, particularly the European Union, while simultaneously maintaining a functional relationship with Russia, upon which it was heavily dependent for energy supplies. This geopolitical tightrope walk reflected the deep divisions within Ukrainian society itself—between a more nationalist, Ukrainian-speaking west that looked toward Europe, and a largely Russian-speaking east and south that favored closer ties with Moscow. This internal dynamic would provide fertile ground for future Russian interference, setting the stage for the escalating tensions that would ultimately lead to confrontation.
