Although the first settlement at the site of present-day Głowno is thought to have appeared in the 11th century, the first town was organized in the early 15th century near a trade route from the Duchy of Masovia, a Polish fief, to the Polish Kingdom. Rawa Mazowiecka feudal lord and Sochaczew podczaszy (deputy cup-bearer) Jakub Głowiński founded Głowno's first Roman Catholic church, which was consecrated on March 11, 1420 as the Church of St. Jacob.
