A movement only arose with the arrival of some 40,000 Jewish refugees from Nazi Germany. While worldwide Reform Judaism originated there, the nature of German communities limited what was known as "Liberal Judaism" to the status of a tendency within unified congregations which had to accommodate traditionalist members. German Liberals were relatively conservative (for example, maintaining mainly-Hebrew liturgy, head coverings for men and separate seating), and found the British Liberal synagogues far too radical. The moderation of the independent nonconformist ones suited them better, and immigrants overwhelmed West London and the others. They also brought along a cadre of 35 Hochschule-trained rabbis, most prominently Ignaz Maybaum and Werner van der Zyl who were aided by Reinhart in finding new posts at Britain. Harmonising ritual and religious approach to a great measure, they made their loosely related communities quite uniform. One that remained independent and strongly clung to German Liberal worship was Belsize Square Synagogue.
