Greece
Tensions soon developed among different Greek factions, leading to two consecutive civil wars. Meanwhile, the Ottoman Sultan negotiated with Mehmet Ali of Egypt, who agreed to send his son Ibrahim Pasha to Greece with an army to suppress the revolt in return for territorial gain. Ibrahim landed in the Peloponnese in February 1825 and had immediate success: by the end of 1825, most of the Peloponnese was under Egyptian control, and the city of Missolonghiput under siege by the Turks since April 1825fell in April 1826. Although Ibrahim was defeated in Mani, he had succeeded in suppressing most of the revolt in the Peloponnese and Athens had been retaken.
