✝ Martin Luther & the Reformation
Martin Luther was a German monk who started the Protestant Reformation in 1517 when he wrote the 95 Theses, criticizing the Catholic Church, especially the sale of indulgences (paying money for forgiveness of sins).
Key idea:
Salvation comes from faith alone, not church actions or money
Bible is the main authority, not the Pope
Effects:
Split in Christianity: Catholic + Protestant churches
Weakened Catholic Church power
Led to religious wars in Europe
Printing press helped spread ideas quickly
🏛 The Three Estates (French Revolution)
French society before the revolution was divided into three groups:
1st Estate: Clergy (Church)
Very small group
Owned land
Paid almost no taxes
2nd Estate: Nobility
Rich aristocrats
Had privileges (no taxes, high status)
Held government/military power
3rd Estate: Everyone else (98% of population)
peasants, workers, bourgeoisie (middle class)
paid almost all taxes
had no political power
Why it matters:
Huge inequality caused anger
Enlightenment ideas made people question this system
Led directly to the French Revolution
🧠 Enlightenment (BIG IDEA)
