Restored political regimes are likely to trend from initial promise to eventual disappointment, or worse. Laffitte viewed the return of the Bourbons favorably at first. He provided financial assistance for the incoming Louis XVIII (1814–1824) and kept his position as governor of the Bank of France during 1814–1820. He was elected to the Chamber of Deputies in 1815 and continued as a deputy throughout the Restoration except for the years 1824–27. Like his fellow elected deputy and banker Casimir Pierre Périer, he took a liberal stance "on the left" and spoke out in the Chamber in support of constitutional monarchy, liberty of the press, freedom of enterprise, competence in state administration and transparency in government financial affairs. As the Bourbon regime became more and more conservative and royalist after 1820, Laffitte became increasingly dissatisfied and outspoken in opposition. With Casimir Perier, he led a spirited opposition in the Chamber in the 1820s against Comte Villèle's handling of the finances of the government's canal construction program. He lost favor in 1825 by voting for Villèle's plan for indemnifying notables for lands confiscated during the Revolution, but regained popular support in 1828 when his daughter, Albine Laffitte, was married to Napoleon-Joseph Ney, the son of the honored Maréchal Michel Ney, duc d'Elchingen, the prince de Moskowa. Things began to go wrong rapidly after Charles X became king in 1824. Fearful of growing liberal and even republican opposition to his government, the king finally acted disastrously in 1829 by installing the ultra-royalist ministry of Prince Jules de Polignac. When the ultra-royalists were defeated in the elections of 1830 the King issued his infamous ordinances of 25 July 1830, suspending freedom of the press, dissolving the Chamber of Deputies, and changing election laws in favor of the landed nobility. The upshot was the July Revolution of 1830.
