The Medici

Explanation:

During the 15th-century, the Medici spent astronomical sums of money on architects and artists, who built and decorated Florence to the total delight of all who lived there.

The ultimatum that Lincoln gave to the states that had seceded from the Union was that he would free all slaves in the Southern states unless they decide to come back to the Union.
This ultimatum was rejected, which made Lincoln issue his Emancipation Proclamation in 1863.
