How was Greece able to become and independent nation in the early 1800s?

Greece gained independence in the early 1800s through a combination of nationalist sentiments, support from foreign powers, and a protracted war of independence against Ottoman rule. The Greek War of Independence began in 1821, fueled by a desire for self-determination and inspired by Enlightenment ideals. Key battles and uprisings, along with significant support from countries like Britain, France, and Russia, ultimately led to the establishment of the independent Greek state in 1830, formalized by the London Protocol.
