As voluntary unincorporated societies, the inns hardly existed apart from their members. This chapter opens with a discussion (‘Motives and Status’) of reasons for the boom in admissions to membership from the mid-sixteenth century and the unsuccessful efforts to regulate and restrict that expansion. The following section (‘Income and Social Origins’) considers economic barriers to membership and the familial origins of those so admitted during the half-century before the Long Parliament, concluding that the inns’ students were generally recruited from a considerably higher social stratum than the student population of the two ancient universities. The chapter moves on to examine the ‘Regional Origins’ of inns of court entrants, showing that while they came from all over England, Wales and Ireland, each society had a distinctive regional recruitment pattern. At the same time, attendance at the inns did much to strengthen the national identity of the future governing elite, rather than merely reinforcing local divisions. A final section (‘Social Tensions and the Exodus of the Gentry’) points to tensions between young gentlemen students and the inns’ lawyer members, contributing to the gradual abandonment of the inns as finishing schools for the upper ranks of society after the civil wars.
