.[ No pope has since been elected at an older age than Clement XII when he was elected.
As a Corsini, with his mother a Strozzi, the new pope represented a family at the highest level of Florentine society, with a cardinal in every generation for the previous hundred years.
On 1 May 1730, several of the cardinals initially settled upon electing Cardinal Gianantonio Davia but had been unable to secure the necessary support. To that end, they refocused their efforts on getting Corsini elected, securing him 31 votes. Corsini, however, was not seriously considered as a candidate until about early July when the candidacy of Pietro Marcellino Corradini started to waver. Meanwhile, the French, Spanish, and Germans were perfectly amenable to Corsini's election.

Soon money poured into Clement XII's treasury, an annual sum amounting to nearly a half million '' scudi'', enabling him to undertake the extensive building programs for which he is chiefly remembered,[ but which he was never able to see.

Art and architecture
A competition for the majestic façade of the Basilica of Saint John Lateran was won by architect Alessandro Galilei. The façade he designed is perhaps more palatial than ecclesiastic, and was finished by 1735.
