Battle · 1386
While Murad I was campaigning in the Balkans, his son-in-law, the Karamanid ruler Alâeddin Bey, attacked the lands of Hamid and occupied Karaağaç, Eğridir and Yalvaç. According to the TDV encyclopedia, Murad I took the field in the spring of 1386; despite Alâeddin Bey's request for peace the two armies met before Konya, at a place called Frenkyazısı, and the Karamanid forces were defeated by the disciplined Ottoman army. Prince Bayezid is said to have earned the name “Yıldırım” (Thunderbolt) for his dash in this battle. Alâeddin Bey took refuge in the citadel of Konya; his plea for peace, made through his wife, was accepted, and Beyşehir passed to the Ottomans.
