Battalion of the Defenders of the Language
The Battalion of the Defenders of the Language was a small militant body established by Jewish students at the Herzliya Hebrew Gymnasium in Tel Aviv in the 1920s to urge Jews in then Mandatory Palestine to use only the Hebrew language. The Battalion campaigned against the use of other languages under the slogan עברי, דבר עברית
Formation
Many early Zionists felt that the revival of the Hebrew language was a critical part of their endeavours. Hebrew was already a well-established language in the land of Israel by the 1920s. However, with the arrival of thousands of immigrants to the land of Israel, as part of the Third Aliyah, many olim continued to speak their native languages, such as Russian and Yiddish.The Battalion of the Defenders of the Language was formed to protect the status of the Hebrew language, and promote its use among these newcomers. Among its most prominent supporters were, a Zionist Hebrew writer, who was one of the founders of the city of Tel Aviv; and Zvi Yehuda Kook, the son of the chief rabbi Abraham Isaac Kook. Many of the activists came from the Herzliya Hebrew Gymnasium, which had long been a centre of pro-Hebrew language activity — its alumni had organised a protest in 1913 against the use of German, which was the language of instruction in the newly-founded Technion institute.
