The First national architectural movement (Turkish: Birinci Ulusal Mimarlık Akımı), also referred to in Turkey as the National architectural Renaissance (Turkish: Millî Mimari Rönesansı), or Turkish Neoclassical architecture was a period of Turkish architecture that was most prevalent between 1908 and 1930 but continued until the end of the 1930s. Inspired by Ottomanism, the movement sought to capture classical elements of Ottoman and Seljuk architecture and use them in the construction of modern buildings. Despite the style focusing on Ottoman aspects, it was most prevalent during the first decade of the Republic of Turkey.
The most important architects of the movement were Ahmet Kemaleddin and Vedat Tek, who pioneered the movement, as well as Arif Hikmet Koyunoğlu and Ottoman-born architect of Italian decent Giulio Mongeri
The movement began in the early 20th-century in the capital of the Ottoman Empire, Constantinople, with the goal of bringing back "Turkish" elements in the construction and design of new buildings. Ever since the late 18th century, European architectural movements such as Baroque, Neoclassical and Rococo architecture were the styles chosen for the majority of imperial buildings built up until the early 20th century.
The first building considered to be built in the Turkish neoclassical style is the Grand Post Office (1905-09), by Vedat Bey in Sirkeci. The building brought back classical Ottoman elements from the 16th century such as two-color stone workmanship and Islamic geometric patterns. This kick-started the movement which was then given the name New Ottoman architecture. After the Young Turk Revolution in 1909, the new government promoted Ottoman revival architecture as a contrast to the many buildings built in western European styles. New government buildings as well as public buildings constructed during the last decade of the empire were mainly designed in the New Ottoman style such as the 7th Eyüp Reşadiye High-school (1911), Beşiktaş Pier (1913), Aviation Martyrs' Monument (1916) as well as the new headquarters for the Committee of Union and Progress, which would later become the first Grand National Assembly building when completed, in 1920. Even after the end of World War I, during the allied occupation of Constantinople, construction of new buildings continued in this style. The Tayyare Apartments, by Ahmet Kemaleddin, were built between 1918 and 1922, during the occupation.
