Rizal visited the United States in 1888, arriving in San Francisco after a week-long quarantine for a cholera epidemic. He traveled across the American continent, impressed by its progress but critical of the lack of racial equality. Rizal then lived in London from 1888 to 1889, studying and annotating Morga's book on Philippine history. While in London, he received both good and bad news from the Philippines and grew as a leader of the Filipino community in Europe.
