The Abbey of Saint Mary de Pratis, more commonly known as Leicester Abbey, was an Augustinian religious house in the city of Leicester, in the English Midlands. The abbey was founded in the 12th century by the 2nd Earl of Leicester, and grew to become the wealthiest religious establishment within Leicestershire. Through patronage and donations the abbey gained the advowsons of countless churches throughout England, and acquired a considerable amount of land, and several manorial lordships. Leicester Abbey also maintained a cell (a small dependent daughter house) at Cockerham Priory, in Lancashire. The Abbey's prosperity was boosted though the passage of special privileges by both the English Kings and the Pope. These included an exemption from sending representatives to parliament and from paying tithe on certain land and livestock. Despite its privileges and sizeable landed estates, from the late 14th century the abbey began to suffer financially and was forced to lease out its estates. The worsening financial situation was exacerbated throughout the 15th century and early 16th century by a series of incompetent, corrupt and extravagant abbots.
