Kırklareli Province (Turkish: {{italics correction|Kırklareli ili) is a province in northwestern Turkey on the west coast of the Black Sea. The province neighbours Bulgaria to the north along a 180km (110miles) long border. It borders the province of Edirne to the west and the province of Tekirdağ to the south and province of Istanbul to the southeast. Kırklareli is the capital city of the province. Its area is 6,459 km2,[1] and its population is 369,347 (2022).[2] The province's and its central city's name means "the land of the forties" in Turkish and it may refer either to the forty Ottoman ghazis sent by the sultan Murad I to conquer the city for the Ottoman Empire in the 14th century or to the forty churches reported to be situated in the region before the Ottoman conquest, as attested by the former name of Kırklareli (Kırk Kilise in Turkish; Σαράντα Εκκλησιές). There is a memorial on a hilltop in Kırklareli city, called "Kırklar Anıtı" (the Memorial of the Forties in Turkish) to honor the Ottoman conquerors (For more on the name's origins, see Kırklareli). The province is bisected by the Yıldız (Istranca) mountain range. The north and northeastern parts of the province are among the least populated and under developed parts of Turkey. The districts to the south and west are more populated because the land is better suited for agriculture and industrial development. The north and eastern parts of the province are dominated by forests. Therefore, forestry is an important means of living in these areas. Fishing is done along the Black Sea coast.
Kırklareli is the capital of the province, but Lüleburgaz is the largest city in the province.
The province was included in the Second Inspectorate General, which established on the 19 February 1934 and extended over the provinces of Edirne, Çanakkale, Kırklareli, Tekirdağ.[3] It was governed by an Inspector General, who had extensive authorities over civilian, military and educational matters.[4] The office of the Inspectorate-General was abandoned in 1948[5] but the legal framework of the Inspectorate-Generals was only abolished in 1952, under the Government of the Democrat Party.[6]
The province of Kırklareli is an important region for viticulture and winemaking. A syrup called "Hardaliye", made of grape, cherry leaves and mustard seeds, is a non-alcoholic beverage special to the region.
Kırklareli province is divided into eight districts (capital district in bold):
