The village was founded around 1540 on the farm of Żuk Leniewicz, who was the first to settle in the area.[2]
Since at least the 17th century, there have been manor buildings in the village, belonging at the end of the century to the sword-bearer Wacław na Jeruzalach Jaruzelski of the Ślepowron coat of arms, and at the end of the 18th century to Wojciech Szepietowski of the Ślepowron coat of arms.[3] After 1800, a brick chapel with a roof made of tiles was built near the manor. This place was referred to as Leniewo Sady.
In a church document from 1775 it was recorded that Leniewo had 109 people living in 28 houses. According to the 1921 census, the village was inhabited by 157 people, among whom 2 were Roman Catholic, 149 Orthodox, and 6 Mosaic. At the same time, 11 inhabitants declared Polish nationality, 146 Belarusian. There were 36 residential buildings in the village.[5]
