Lazarus contributed toward shaping the self-image of the United States as well as how the country understands the needs of those who emigrate to the United States. Her themes produced sensitivity and enduring lessons regarding immigrants and their need for dignity.[40] What was needed to make her a poet of the people as well as one of literary merit was a great theme, the establishment of instant communication between some stirring reality and her still hidden and irresolute subjectivity. Such a theme was provided by the immigration of Russian Jews to America, consequent upon the proscriptive May Laws of 1882. She rose to the defense of her ethnic compatriots in powerful articles, as contributions to The Century (May 1882 and February 1883). Hitherto, her life had held no Jewish inspiration. Though of Sephardic ancestry, and ostensibly Orthodox in belief, her family had till then not participated in the activities of the synagogue or of the Jewish community. Contact with the unfortunates from Russia led her to study the Torah, the Hebrew language, Judaism, and Jewish history.[20] While her early poetry demonstrated no Jewish themes, her Songs of a Semite (1882) is considered to be the earliest volume of Jewish American poetry.[41]
A review of Alide by Lippincott's Monthly Magazine was critical of Lazarus's style and elements of technique.[42]
