Around 1880, according to collective memory, a pogrom struck Siahkal's Jewish community. Many were killed. Others faced forced conversion to Islam. Those who could, fled to Rasht. The survivors who remained in Siahkal found themselves increasingly isolated, a shrinking minority in a town where they had once been a self-sustaining community. In the decades that followed, remaining members converted to various faiths -- some to Islam, some to the Baha'i Faith. Others joined the Marxist movement that swept through Gilan in the early 20th century. The Marxist insurrection of 1921 and subsequent Soviet occupation further disrupted communal life. When Israel was established in 1948, the last practicing Jews of Siahkal emigrated, ending a presence that had lasted centuries.

Siahkal sits in the Central District of Siahkal County, serving as capital of both the county and the district. The city's population reached 19,924 by the 2016 census, its people predominantly Gilak, speaking the Gilaki language. The landscape surrounding the town is dramatic: waterfalls cascade through dense forest at Lonak and Baba Vali. The Dorfak Mountain rises above the treeline. Ancient caravanserais like Ti Ti mark old trade routes through the mountains, and the ruins of Garmavar Castle and Kutul Shah Castle hint at centuries of local power struggles. The road from Siahkal to Deylaman winds through forest so dense it feels primordial, the kind of landscape where communities could survive in isolation for centuries precisely because no one could easily reach them.

The terrain around Siahkal transitions from mountain forest to cultivated lowland within a few kilometers. Rice farms fill the valleys below town, their flooded paddies reflecting the sky in spring planting season. Mineral water springs bubble up from the earth in multiple locations. The Pashuran Park and Pool draw visitors from across the region, and a weekly market remains the commercial heartbeat of the town. The Gilarkesh Rock Shelter preserves evidence of far older human habitation, and shrines to various saints and prophets -- Qader the Prophet, Baba Vali, Saleh and Sultan Hussein -- dot the surrounding hills, markers of the layered spiritual history of a place where faiths have coexisted and collided for centuries.

Modern Siahkal sits at a crossroads between tradition and change. Islamic Azad University and Payame Noor University both maintain campuses here, bringing students and contemporary culture to a town whose roots reach deep into the ancient past. The Azodi House preserves traditional Gilaki architecture. Imamzadeh Mustafa draws pilgrims. But the story that makes Siahkal unique -- the Jewish community that believed itself descended from royalty, that endured for centuries in mountain isolation, and that was destroyed by the forces of modern history -- is the one that resonates most. Their synagogues are gone. Their descendants live in countries their ancestors never saw. The town continues, its forests and waterfalls unchanged, the mountains indifferent to the human dramas they have witnessed.
