Mikhail, or Hamud Bey Sharvashidze-Chachba, from the House of Sharvashidze, (born 1806, died 1866) was the head of state of the Principality of Abkhazia and reigned from 1823 to 1864.

[1] Mikhail, who was Orthodox Christian, came to power at a time when Abkhazia had only recently been declared a protectorate of Russia, as a result of the 1810 manifesto of Tsar Alexander I.

He was subsequently exiled to Voronezh, in Russia – an act which was vastly unpopular with the Abkhaz people.

Mikhail's deportation, and death not long after, also marked the beginning of the end for Abkhazian self-governance for the next 140 years.

In 1866, a popular uprising declared Mikhail's son Giorgi Prince, but this was short-lived.
