Botkyrka Municipality is a municipality in Stockholm County in east central Sweden, not far from the capital Stockholm. Its seat is located in the town of Tumba.In 1971 Grödinge was merged with Botkyrka and in 1974 Salem was added. The Salem part was already in 1983 split off again and a new Salem Municipality was formed.HistoryThe municipality is named after Saint Botvid, a Christian missionary during the 12th century. Saint Botvid is shown on the seal and coat of arms of Botkyrka Municipality, where he carries an axe and a fish. Another remnant of Botkyrka's Christian medieval history is the Botkyrka church, made of stone.Botkyrka, particularly Northern Botkyrka, has one of the highest percentages of first and second generation immigrants in Sweden. 56.4% the population has at least one parent born in another country. This gives the municipality a multi-cultural atmosphere with for example a big Syriac Orthodox Church in Hallunda and a mosque in Fittja.Politically the municipality is primarily Social Democratic, that has governed Botkyrka for a long period except 3 years in the early 1990th. However, with less seats the party now governs together with The Green Party, and The Left Party. There have also been several local parties. For a long period a local party called Botkyrkapartiet (The Botkyrka Party) has held several seats. A party was also active from mid 1980th to mid 1990th with only one purpose - to prevent the exploitation of the small airfield, F18, in Tullinge to become a commercial airport in the 1980s. In the election 2010 a local party for the area of Tullinge got 6 seats on the agenda of separating Tullinge from Botkyrka as a separate municipality.
