Thrasyvoulos Zaimis

Thrasyvoulos Zaimis (Θρασύβουλος Ζαΐμης, 1822–1880) was a Greek politician and the 21st Prime Minister of Greece. Zaimis was born in Kerpini, Kalavryta on 29 October 1822, the son of Andreas Zaimis, a soldier and government leader before the recognition of Greece's freedom from the Ottoman Empire. Zaimis studied law in France and was first elected to the Hellenic Parliament in 1850. He served four terms as President of Parliament and also as minister in several governments.

In 1864, he was the representative of the Greek government who accepted the cession of the Ionian Islands from the British government, a gift that coincided with the enthronement of King George of Greece. Zaimis served two terms as prime minister and died in Athens on 27 October 1880. Thrasyvoulos Zaimis was the father of Alexandros Zaimis, also a Prime Minister of Greece.
