**Zviad Gamsakhurdia**, the first elected president of Georgia, faced opposition from Eduard Shevardnadze, a prominent Georgian politician and former Soviet foreign minister. Shevardnadze, who had initially supported Gamsakhurdia but grew critical of his leadership, sided with rebel forces in a civil war that eventually led to Gamsakhurdia's overthrow and the establishment of Shevardnadze as the country's new leader.
