Power corrupts, they say. Throughout history, certain figures have risen to absolute control, leaving behind legacies so divisive that even centuries later, we cannot agree on what they truly represent. Were they visionary leaders who transformed the world? Or tyrants whose ambitions brought nothing but suffering? The answer, it seems, depends entirely on who you ask.
These leaders changed entire civilizations, reshaped borders, and influenced millions of lives. Their decisions still echo in our modern world, in systems we use, wars we remember, and scars that haven’t fully healed.
Joseph Stalin: The Soviet Strongman Who Reshaped Russia

Stalin has arguably made a greater impact on the lives of more individuals than any other figure in history, according to scholarly assessments. Yet this impact came at an unimaginable cost. The Soviet dictator’s rule from the late 1920s until his death in 1953 transformed the USSR into an industrial superpower while simultaneously crushing millions beneath his brutal regime.
According to a recent Levada-Center poll, Stalin’s popularity is actually rising in modern Russia, a phenomenon that bewilders many Western observers. Even now, some seventy years after Stalin’s death, the Russian army’s invasion of Ukraine has underscored the persistence of Stalin’s legacy in the Kremlin. His collectivization policies led to devastating famines, with the Soviet Union experiencing a major famine which peaked in the winter of 1932-1933, with 5-7 million deaths.
Stalin’s security services suppressed a nationalist insurgency by deporting over 250,000 people to Siberia from western Ukraine alone. Research from the Journal of Politics demonstrates communities subjected to a greater intensity of deportation in the 1940s are now significantly less likely to vote for pro-Russian parties, showing how historical violence shapes political preferences across generations.
Mao Zedong: China’s Revolutionary Architect

In modern China, Mao is widely regarded as a national hero who liberated the country from imperialism, becoming an ideological leader within the international communist movement. Outside China’s borders, though? That’s a completely different story. The founder of the People’s Republic remains one of history’s most polarizing figures.
Beginning with Deng Xiaoping after 1978, official historiography has drawn a distinction between Mao the Cultural Revolutionary and Mao the architect of Chinese Marxism. This careful separation allows modern China to honor his revolutionary achievements while distancing itself from his catastrophic errors. In present discourse, he has come to be seen not as a liberator, at least outside the People’s Republic, but as a tyrant and bringer of starvation and misery to the peasant class.
The Great Leap Forward and Cultural Revolution brought devastation to countless lives. Interestingly even within China, the degree of presence that the market forces have is a cruel joke on Mao’s absolute hatred of capitalism. His portrait still overlooks Tiananmen Square, watching over a nation that has embraced the very economic systems he despised.
Napoleon Bonaparte: Between Enlightenment and Tyranny

Here’s where things get really messy. Napoleon created a new form of government in France, reshaped the boundaries of Europe, and influenced revolutionaries and nationalists the world over, arousing controversies that continue today. Was he democracy’s champion or just another power-hungry dictator wrapped in revolutionary rhetoric?
The Napoleonic Code was adopted by something like 20 countries around the world, including countries as far-flung as Japan, Iran before the Iranian Revolution, and many continental European countries. That’s a legacy that extends far beyond the battlefield. It’s believed that up to six million people died during the Napoleonic Wars, a staggering toll that overshadows his administrative genius.
Napoleon was a political animal who loved power and was motivated by the quest to have power, to hold power and to exercise power. His personality, revealed through 70,000 letters he wrote, shows a man obsessed with domination. Historians debate whether Napoleon was an enlightened despot who laid the foundations of modern Europe or a megalomaniac who wrought greater misery than any man before the coming of Hitler.
Genghis Khan: The Conqueror Who Connected Worlds

Genghis Khan is remembered as a backwards, savage tyrant in Russia and the Arab world, while recent Western scholarship has begun to reassess its previous view of him as a barbarian warlord, yet he was posthumously deified in Mongolia where modern Mongolians recognise him as the founding father of their nation. Talk about divided opinions.
The Mongol conqueror built the largest contiguous empire in history, stretching from the Pacific to Eastern Europe. The Mongol army under Genghis killed millions of people, yet his conquests also facilitated unprecedented commercial and cultural exchange over a vast geographical area. This duality defines his legacy.
In modern Mongolia, his rehabilitation has been extraordinary. Less than two years after the 1990 revolution, Lenin Avenue in the capital Ulaanbaatar was renamed Chinggis Khan Avenue, and Mongolia has since named Chinggis Khaan International Airport and erected a large statue in Sükhbaatar Square. Modern Mongolians tend to downplay Genghis’s military conquests in favour of his political and civil legacy, viewing the destructive campaigns as a product of their time.
Oliver Cromwell: England’s Divisive Protector

Oliver Cromwell is celebrated by some as a champion of democracy and religious freedom, while others view him as a dictator who ruled with an iron fist. The man who helped execute King Charles I and established the Commonwealth remains deeply controversial, especially across the Irish Sea.
Cromwell is fiercely criticized for his brutal conquest of Ireland, which included killing up to 50% of the native population, sending the country into famine, and taking 50,000 native Irish as indentured laborers. In Ireland, his name still evokes bitter memories. In England, he’s viewed more ambiguously as both a republican hero and an authoritarian figure who ultimately failed to create a lasting democratic system.
Vladimir Putin: The Modern Autocrat

Vladimir Putin has run Russia since 1999, making him the longest-running leader since Stalin. That comparison alone tells you plenty about his controversial status. Many critics have argued that Putin has transformed the country into an authoritarian dictatorship, as evident by the 2020 constitutional referendum that gave him more power and drew accusations of corruption.
Putin has been issued an arrest warrant by the International Criminal Court for various crimes against humanity, particularly regarding actions in Ukraine. He controls most major media outlets in Russia and violently suppresses independent journalists who speak out against his corruption and dictatorial rule. Yet within Russia, his support remains substantial among certain segments of the population who credit him with restoring national pride.
His legacy is still being written, which makes him uniquely controversial. We’re watching history unfold in real time, unable to fully grasp what his long rule will ultimately mean for Russia and the world.
