Boisbelle-Henrichemont
The land of Boisbelle, in Berry, was part of the "sirerie" of
Sully, which happened to be a franc-alleu. Marie de Sully, heiress,
married Charles d'Albret, constable of France (killed at Agincourt
in 1415). Their descendant Marie married Charles de Cleves, comte
de Nevers in 1528, and their grand-daughter Henriette de Cleves married
Louis of Gonzaga, whose son Charles sold Boisbelle and Sully in 1597
to Maximilien de Béthune, the famous minister of Henri IV.
Sully was made a duchy peerage in 1606 (Levantal 915 says that Sully
was purchased in 1602 from the duc de Thouars). Its possessor decided to
found a new town, and named it Henrichemont (a pun on "Henri" and "riche")
to honor his king.
LETTERS OF PATENT:
The privileges of sovereignty (including the right to mint coins) were
confirmed by Letters Patent of April 1598, September 1608, Dec 1608,
September 1635 and January 1644. Letters patent of June 6, 1664 state:
"la seigneurie de Boisbelle et Henrichemont est et demeure comme
elle a été de tous temps, en titre et prééminence
de principauté, sans reconnaissance d'aucun supérieur
pour la foi et hommage; de justice souveraine sans appel, sous l'autorité
du duc de Sully et de ses successeurs et de tous les autres droits
qui appartiennent à seigneurs souverains".
MINTING COINS
Sully and his son minted coins under the title of "prince souverain
d'Enrichemont et de Boisbelle". The land was united to the crown in 1766,
after a contract of Sep. 24, 1766 exchanged it for other lands in the king's
possession. At that time, the only taxes in Boisbelle were a salt-tax
(gabelle) and a tax on tobacco. The population was around 8,000, and the
annual income for the duc de Sully was around 30,000 livres (Archives Parlementaires,
1e série, vol. 31, p. 399). The lands ceded in exchange were worth
twice as much as Henrichemont, the premium reflecting the value to the
king of buying a sovereign land.
