Rabbi Avraham Mordechai Alter (1866–1948), universally known as the Imrei Emes, was the third Grand Rabbi of the Ger Chassidic dynasty. Leading the movement for over forty years, he was the primary architect who transformed Ger into the largest, most powerful, and most organized Chassidic group in pre-WWII Europe.

He was a monumental visionary who co-founded the Agudat Yisrael movement, revolutionized Orthodox Jewish education, and miraculously survived the Holocaust to rebuild his shattered dynasty from the ashes in Jerusalem.

Early Life and Rise to Leadership

• Lineage: Born in Góra Kalwaria (Ger), Poland, he was the eldest son of the fourth Gerrer Rebbe, Rabbi Yehuda Aryeh Leib Alter (the Sfas Emes), and the great-grandson of the dynasty's founder, the Chiddushei HaRim.

• Assuming the Mantle: When his father passed away in 1905, Rabbi Avraham Mordechai was highly reluctant to take over. However, under pressure from the community's elders, he accepted the position.

• The Mass Movement: Under his stewardship, Ger grew exponentially. Before World War II, it was estimated that he had upwards of 200,000 followers, making him one of the most influential Jewish leaders on earth. He opened dozens of Shtieblach (small synagogues/study halls) across Poland.

Global Leadership and Agudat Yisrael

The Imrei Emes recognized that traditional Jewry faced unprecedented threats from modern secularism, socialism, and political shifts. Rather than retreating into isolation, he chose to organize.

• Founding Agudat Yisrael: In 1912, he became one of the primary founders of Agudat Yisrael, a global political and social movement aimed at uniting Chassidic, Lithuanian, and Western European Orthodox Jews under the guidance of Torah sages (Moetzes Gedolei HaTorah).

• Revolutionizing Education: He was a fierce champion of education. Alongside his student Rabbi Meir Shapiro, he enthusiastically endorsed the Daf Yomi initiative (the global daily study of a Talmud page). He was also a crucial backer of Sarah Schenirer and her Bais Yaakov movement, which pioneered formal Torah education for Orthodox girls—a radical shift at the time.

• Love for Israel: Unlike many of his contemporary European peers, the Imrei Emes possessed a deep love for the Land of Israel. He visited Mandatory Palestine five times (in 1921, 1924, 1927, 1932, and 1935), urging his followers who had the financial means to emigrate and purchase land there. He even acquired property in Jerusalem and established the Sfas Emes Yeshiva there in 1925.

World War II: The Miraculous Escape

When Germany invaded Poland in September 1939, the Nazi regime specifically targeted the Imrei Emes due to his massive influence.

• The Hunt: He was forced into hiding in Warsaw under an assumed name while the Gestapo actively hunted for him.

• The Rescue: In a daring, highly complex operation in 1940 orchestrated by his sons and international activists, the aging and sickly Rebbe was successfully smuggled out of Nazi-occupied Poland. Traveling through Italy and Egypt, he safely reached Jerusalem.

• The Heartbreak: While he survived, the vast majority of his family, including his children, grandchildren, and hundreds of thousands of his Chassidim, were murdered in the Holocaust.

Rebuilding from the Ashes and Passing

Arriving in Jerusalem heartbroken and physically weak, the Imrei Emes refused to despair. He famously declared that the destruction of European Jewry meant the spiritual center must now shift permanently to the Land of Israel. He spent his final years laying the groundwork for the modern rebirth of the Ger dynasty.

He passed away at the age of 82 on the festival of Shavuot in June 1948, right in the middle of the Israeli War of Independence. Because Jerusalem was under heavy siege and Arab sniper fire made the traditional Mount of Olives cemetery completely inaccessible, he was buried in a makeshift grave in the inner courtyard of his yeshiva, the Sfas Emes Yeshiva, in central Jerusalem. His gravesite remains a major pilgrimage site today.

Succession and Dynasty

The Imrei Emes left behind a legacy that shaped the modern Haredi world. Because of his efforts, three of his sons survived the war or were already in Israel, and each consecutively succeeded him as the Grand Rabbi of Ger, rebuilding the dynasty into the empire it is today:

1. Rabbi Yisrael Alter (the Beis Yisrael) – Fourth Rebbe (1948–1977)

2. Rabbi Simchah Bunim Alter (the Lev Simchah) – Fifth Rebbe (1977–1992)

3. Rabbi Pinchas Menachem Alter (the Pnei Menachem) – Sixth Rebbe (1992–1996)

(Note: His grandson, Rabbi Yaakov Aryeh Alter—son of the Lev Simchah—is the current Gerrer Rebbe).
