] But what is the Ministry of All the Talents?

A coalition of Whig factions and arch-Tories under Lord Grenville, Charles James Fox, and Lord Sidmouth that governed for about 13 months after Pitt's death in January 1806. It passed the act abolishing the slave trade, but the government fell apart after Fox died and Grenville refused to promise George III that he would not introduce legislation increasing the civil rights of Roman Catholics. Grenville basically quit before the King could fire him.
