Ukmergė (; previously Vilkmergė; ) is a city in Vilnius County, Lithuania, located northwest of Vilnius, with a population of about 20,000. Etymology and variant names The city took its original name Vilkmergė from the Vilkmergėlė River, which was initially called Vilkmergė and assumed a diminutive form after the growth of the settlement. It is commonly thought that the name may be translated as "she-wolf", from the combination of Vilkas (wolf) and Merga (maiden). More likely the second root of the dual-stemmed name is the verb merg-/merk- meaning "to submerge" or "to dip". According to local legend, Vilkmergė was a girl raised by wolves, who bridged the divide between animals and humans, in the same way as Rudyard Kipling's Mowgli. The folk etymology of "Ukmergė", by contrast, is "farm girl" (Lith. ūkis = farm). The original name has been adopted by the local soccer team, "Vilkmergė Ukmergė" as well as popular HBH Vilkmergė beer.

History Early history Ukmergė was first mentioned in 1225, and named as a settlement in 1333. It was essentially a wooden fortress that stood on a hill, near the confluence of the Vilkmergė River and the Šventoji River. Ukmergė was attacked by the Teutonic Knights and the Livonian Order in 1333, 1365, 1378, 1386, and even in 1391, already after the Christianization of Lithuania in 1387. During the last attack, Ukmergė was burned to the ground and had to be completely rebuilt. The region began to adopt Christianity, along with the rest of Lithuania, in 1386. In the following year, 1387, its first Catholic church, St. Peter and St. Paul, was built. It was one of the first Roman Catholic churches established in Lithuania. The town was granted municipal rights at some time after the Battle of Wiłkomierz in 1435, and written sources dating from 1486 referred to it as a city. King Sigismund the Old confirmed these rights. During the times of the Polish–Lithuanian Commonwealth, the city had been the center of powiat in the Vilnius Voivodeship. In 1655, the Swedish and Russian armies plundered the city. Because of these incessant wars, the growth of Ukmergė suffered many setbacks. Jews began to settle in the city in the late
