Historian Gavin Schaffer wrestles Jewish history away from the question of what others have thought about Jews, focusing instead on the experiences of Jewish people themselves.

Exploring the complexities of inclusion and exclusion, he shines a light on groups that have been marginalised within Jewish history and culture, such as queer Jews, Jews married to non-Jews, Israel-critical Jews and even Messianic Jews, while offering a fresh look at Jewish activism, Jewish religiosity and Zionism.

Weaving these stories together, Schaffer argues that there are good reasons to consider Jewish Britons as a unitary whole, even as debates rage about who is entitled to call themselves a Jew. Challenging the idea that British Jewish life is in terminal decline, An unorthodox history demonstrates that Jewish Britain is thriving and that Jewishness is deeply embedded in the country's history and culture.
