France had recovered from the strain and disorganization, the wars, the killings, the horrors, of two decades of disruption. It was at peace throughout the period. It paid a large war indemnity to the winners, but managed to finance that without distress; the occupation soldiers left peacefully. France's population increased by 3 million, and prosperity was strong from 1815 to 1825, with the depression of 1825 caused by bad harvests. The national credit was strong, there was significant increase in public wealth, and the national budget showed a surplus every year. In the private sector, banking grew dramatically, making Paris a world center for finance, along with London. The Rothschild family was world-famous, with the French branch led by James Mayer de Rothschild (1792–1868). The communication system was improved, as roads were upgraded, canals were lengthened, and steamboat traffic became common. Industrialization was delayed in comparison to Britain and Belgium. The railway system had yet to make an appearance. Industry was heavily protected with tariffs, so there was little demand for entrepreneurship or innovation.
