In 1811, Hamburg became part of the French Empire. The legal reorganization also led to the dissolution of the Triple Congregation. In 1812, the German-Israelite Congregation was founded in the city. With 6,300 members, it was the largest Jewish congregation in Germany at the time. The disappearance of “conservative” influence from Altona is considered a prerequisite for the development of Reform Judaism in Hamburg.
In 1841, congregation rabbi Isaak Bernays publicly prohibited the use of a prayer book published by the Temple Association. The ensuing dispute illustrates the religious differentiation in the nineteenth century: A power struggle ensued between reformers and representatives of “law-abiding” Judaism. Even among the supporters of reform, there were disputes about the extent of liturgical changes, such as the abridgement of traditional prayer texts.
In 1818, the Temple Association rented premises in Hamburg-Neustadt and set up the first “temple” – in contrast to the term “synagogue.” The Association gained more and more members, causing a shortage of seating. In 1844, a new building was dedicated on Poolstrasse. The reformist approach was also evident in the building’s design, featuring a common entrance for women and men and a built-in organ – the first in a German synagogue.

The neo-Romanic building stood in a converted backyard, but was visible from the street. The building and the front houses belonged to the temple association. Restrictions on the acquisition of real estate by Jews had only been abolished in 1842. Religious services were held there until 1931.

Kley headed the reform-oriented Israelite Free School in Hamburg from 1816. There he organized the first reform services, resulting in the founding of the Temple Association. From 1817 to 1840, he was one of the first two preachers of the Temple. He is considered a pioneer of modern synagogue preaching.

Isaak Bernays was rabbi of the German-Israelite Congregation from 1821. As a pioneer of modern Orthodoxy, he rejected Reform Judaism. At the same time, he introduced secular subjects into Jewish schools. With his German-language sermons, he set an example for the new beginning of an Orthodox rabbinate.

In 1841, the prayer book of the Temple Association of 1818 was published in a revised edition. Some of the traditional texts were reworded in line with the spirit of reform. For example, the request for a return to Israel was omitted. The temple would now stand in Hamburg and would not need to be rebuilt in Jerusalem.
