beginning in the 16th century, the Persian Empire and the Ottoman Empire subjugated the eastern and western regions of Georgia, respectively.
The rulers of regions which remained partly autonomous organized rebellions on various occasions. However, subsequent Persian and Ottoman invasions further weakened local kingdoms and regions. As a result of incessant wars the population of Georgia dwindled from 5 million in the 13th century to 250,000 inhabitants at the end of the 18th century.
