Bórojov’s career began in the family, with his father; a Hebrew teacher who played in the Lovers of Zion party. Soon, his love for the brilliant minds of all times, from Greek thinkers to contemporaries like Marx and Engels, ended up defining his adherence to politics. First he joined the Social Democratic Party of Russia, but in May 1901 he was expelled for his position against the so-called Jewish question.
In 1905 he joined the Poale Zion movement, of which he was secretary years later. In 1914, with the outbreak of World War I, he settled in the United States and returned to Europe when his Russian brothers organized the revolution against the Czar.
Some of his works such as “The Character of Jewish Intelligence” and “The National Question and the Class Struggle” served as a doctrine for later Zionist thinkers, trying to eliminate the contradictions between Zionism and socialism.
He died in 1917 due to a pneumonia.
