When and Why Immigrants Came Through Ellis Island

When: The Great Wave (1892–1924)

**Peak years:** 1900–1914 (1M+ annually). **Sharp decline after 1924** quotas. Post-1924: mostly detainees, deportees, displaced persons (WWII), and quota immigrants.

Why: The Convergence of Forces

1. U.S. Immigration Law: Federal laws (1882, 1891, 1903, 1907, 1917, 1924) mandated **medical, legal, and literacy inspections**. Ellis was the enforcement arm.
2. Steamship Company Compliance: Lines (Cunard, White Star, Hamburg-America) **pre-screened** passengers in Europe (fines for rejects). They **docked at Ellis** for efficient federal processing.
3. Port of New York Dominance: **70%+ of all immigrants** entered via NY Harbor. Ellis (in Upper Bay) was the **custom-built, high-capacity facility** (peak: 5,000–10,000/day).
4. Processing Infrastructure: **Great Hall** (registry), **medical exam lines** (6-second "glance" for trachoma, favus, lameness), **legal boards** (29 questions), **detention dorms**, **hospital** (22 buildings). Unmatched scale.
5. Federal Control: Centralized **exclusion** (contract laborers, criminals, "likely public charges," anarchists, Asians post-1917). **Symbol of sovereign border control**.

Who Came

**1892–1914:** Southern/Eastern Europeans (Italians, Jews, Poles, Slavs, Greeks).
**Post-1924:** Quota-limited Europeans; refugees (Jews 1930s, DPs 1940s); War Brides (1945+).

Ellis Island was the **bureaucratic gateway** where American immigration policy met the huddled masses—**the filter, not the magnet**.
