Sefer Chassidut Beit Avraham – Chassidei HaRa'ayah Kook Be'ir Slonim / ספר חסידות בית אברהם - חסידי הראי"ה קוק בעיר סלונים / ברחבי פולין

A captivating historical and ideological research volume detailing an overlooked chapter in pre-war European Jewry: the dozens of traditional Chassidic families across Poland and Slonim who embraced the Zionist-spiritual teachings of Rabbi Avraham Yitzchak Kook (the first Chief Rabbi of Israel). Moving chronologically from the movement's rise in 1930 (תרפ"ץ) to its tragic end during the Holocaust in 1943 (תש"ג), the book gathers rare documentation, personal letters, and deep ideological essays exploring how these communities synthesized intense, classical Chassidic fervor with modern national awakening.
