1716, also between 1726 and 1730 although else the Swedish regulation was continued by the Prussian administration. Only after the Prussian Edict of Emancipation of 11March 1812, which granted Prussian citizenship to all Jews living in the kingdom, did a Jewish community emerge in Stettin, with the first Jews settling in the town in 1814. Construction of a synagogue started in 1834; the community also owned a religious and a secular school, an orphanage since 1855, and a retirement home since 1893. The Jewish community had between 1,000 and 1,200 members by 1873 and between 2,800 and 3,000 members by 192728. These numbers dropped to 2,701 in 1930 and to 2,322 in late 1934. After the Franco Prussian war of 1870–1871, 1,700 French POWs were imprisoned there in deplorable conditions, resulting in the deaths of 600; after the Second World War monuments in their memory were built by the Polish authorities. Until 1873, Stettin remained a fortress. When part of the defensive structures were levelled, a new neighbourhood, Neustadt ("New Town") as well as water pipes, sewerage and drainage, and gas works were built to meet the demands of the growing population. Stettin developed into a major Prussian port and became part of the German Empire in 1871. While most of the province retained its agrarian character, Stettin was industrialised, and its population rose from 27,000 in 1813 to 210,000 in 1900 and 255,500 in 1925. Major industries that flourished in Stettin from 1840 were shipbuilding, chemical and food industries, and machinery construction. Starting in 1843, Stettin became connected to the major German and Pomeranian cities by railways, and the water connection to the Bay of Pomerania was enhanced by the construction of the Kaiserfahrt (now Piast) canal. The city was also a scientific centre; for example, it was home to the Entomological Society of Stettin. On 20 October 1890, some of the city's Poles created the "Society of Polish-Catholic Workers" in the city, one of the first Polish organisations. In 1897, the city's ship works began the construction of the pre-dreadnought battleship Kaiser Wilhelm der Grosse. In 1914, before World WarI, the Polish community in the city numbered over 3,000 people, contributing about 2% of the population. These were primarily industrial workers and their families who came from the Poznań (Posen) area and a few local wealthy industrialists and merchants. Among them was Kazimierz Pruszak, director of the Gollnow
