"As we have been doing for the past 21 years, we will hopefully deliver upon our promises one by one," he said, referring to the November 2002 elections, which swept his AK Party into office.
"We will save our democracy from the current constitution, which is a product of the (1980) coup, and strengthen it with a libertarian, civilian and inclusive one," he further pledged.
"We will continue to develop our country through investment, employment, production, exports, and a current account surplus. We are determined to put Ghazi Mustafa Kemal's (Ataturk) principle of 'Peace at home, Peace in the world' into practice in its true meaning," he added.
"We promise to work with all our strength to protect the glory and honor of the Republic of Türkiye, to promote its reputation, and to glorify its name in the world for five years," he added.
The ceremony was attended by high-level officials, including 50 heads of state, 13 prime ministers, parliamentary, and ministerial-level officials, and representatives of international organizations, including NATO, the Organization of Turkic States, and the Organization of Islamic Cooperation.
