As a journalist, he didn’t limit himself to the national press. On 8 September 1877, he published an article entitled "Poland and Russia" in the Californian daily newspaper "Daily Evening Post”. He described and condemned the two-faced policy of the Russian authorities in the article. According to Sienkiewicz, Russia acted as a defender of the Slavs in the Balkans and at the same time persecuted Poles on the territory of the Kingdom of Poland.
He also traveled a lot which inspired him to create many works including “Letters from a Journey” and “Litwos’ Letters from a Journey”. His travels were financed by Gazeta Polska (The Polish Gazette) in exchange for a series of travel essays. His articles also appeared in other newspapers, for example, “The Weekly Review” and “Learned and Literary Guide”, where he described the situation of American Polonia.
As a writer, Sienkiewicz was a strong supporter of Polish Positivism, endorsing constructive, practical characters such as an engineer and a conservative. He wrote such works as "Janko the Musician" in 1879 or “With Fire and Sword” in 1883–84. Later, in the early 1900s, he fell into mutual hostility with the Young Poland movement in Polish literature and as an outcome, his internationally best-known work “Quo Vadis” was written. It is set in Nero's Rome. His books have been filmed several times, including Hollywood's 1951 version of “Quo Vadis” which received the most recognition.
