Turkish President Recep Tayyip Erdogan appealed for national unity Monday after winning a historic runoff election that extended two decades of his transformative but divisive rule until 2028.

The 69-year-old overcame Turkey's worst economic crisis in a generation and the most powerful opposition alliance to ever face his Islamic-rooted party on his way to his toughest election win.

Streets erupted in car-honking jubilation and tributes poured in from across the world as Turkey's most important leader in modern history led a sea of supporters in celebratory song outside his presidential palace in Ankara.
