The municipality of Kodeń, located in the Lublin Voivodeship within Biała Podlaska County, has a rich history dating back to the times of the Kingdom of Poland, when it was established on January 13, 1870. Its seat, the town of Kodeń, lost its town rights, and the municipality was transformed into a rural administrative unit. In 1912, the municipality was incorporated into the newly created Chełm Governorate, and during the interwar period, it was part of the Lublin Voivodeship. In 1921, 1,639 people lived there, and during World War II, the territory of the abolished Kostomłoty municipality was incorporated into Kodeń. The municipality was abolished in 1954 but was reinstated on January 1, 1973, as part of subsequent administrative reforms. The municipality covers an area of 150.33 km², of which 65% is agricultural land and 27% is forested. Kodeń is known for its high percentage of Orthodox believers and is home to three village districts (sołectwa) and a monastery in Kostomłoty, highlighting the area's rich cultural heritage. The municipality of Kodeń consists of several village districts, including Kodeń, Kopytów, Kostomłoty, and Elżbiecin, as well as smaller settlements. As of December 31, 2021, the population of the municipality is 3,441. It borders Belarus, which contributes to its cultural enrichment and diversity. Interestingly, Kodeń, due to its Orthodox traditions, attracts pilgrims, giving it a distinctive spiritual character. The municipality is an important focal point in the context of local traditions and the history of the region.
