Chuts is the name applied to Jews who immigrated to London from the Netherlands during the latter part of the 19th century. They typically came from Amsterdam and practised trades they had already learned there, most notably cigar, cap and slipper making.
They settled mostly in a small system of streets in Spitalfields known as the Tenterground, formerly an enclosed area where Flemish weavers stretched and dried cloth on machines called tenters (hence the expression "on tenterhooks"). By the 19th century, the site had been built upon with housing, but remained an enclave where the Dutch immigrants lived as a close-knit and generally separate community. Demolished and rebuilt during the twentieth century, the area is now bounded by White's Row, Wentworth Street, Bell Lane and Toynbee Street (formerly Shepherd Street).
Following the assassination of Tsar Alexander II of Russia in 1881, many thousands of Jewish refugees, fleeing political unrest in Eastern Europe, arrived in the East End of London, including the Tenterground, by which time the Chuts had begun to disperse. Significantly, the successful introduction of machinery for the mass-production of cigarettes ultimately led to the collapse of the cigar-making economy on which the Chuts community depended. Many Chuts returned to improved conditions in Amsterdam, some emigrated further afield to places such as Australia and the United States, some assimilated into other Jewish families, and some eventually lost their Jewish identity altogether.
There was distinct rivalry between the Chuts and the later Jewish immigrants, not least because the Chuts had arrived as city-dwellers, with useful industrial skills, and by 1881 had already learned to speak English, whereas the later immigrants were generally impoverished rural workers who had to learn new trades in the notorious sweatshops and, arriving penniless and in great numbers, drew attention to the problem of immigration which resulted in the Aliens Act of 1905.
Furthermore, the Chuts were treated with suspicion by other Jews because the former had developed specific customs and practices, many of their families having lived in Amsterdam since the first synagogues were established there in the early years of the 17th century. Uniquely in Amsterdam, Ashkenazim (so-called "German Jews") and Sephardim (so-called "Spanish Jews") lived in close proximity for centuries, resulting in a cultural blend not found elsewhere. Most remarkably, the Dutch Jews were well accustomed to the sea, and ate seafoods considered not kosher by other Jewish communities.
