BUENOS AIRES, (1) the most important province in the Argentinian republic in terms of economic wealth (cattle raising, wheat farming, and industriy) and concentration of population (13,827,203 out of a total population of 36,60,130 in 2001); (2) federal capital of the Republic of Argentina, general population 2,768,772 (2001). The Jewish population of the capital and its suburbs ("Greater Buenos Aires") was estimated at 180,000–200,000 in 2004.
The first colony of the *Jewish Colonization Association (ICA) – Maurício (1891) – was established in Buenos Aires and was followed by the Baron Hirsch colony (1904–05) a few years later. In the early 21st century there were many small Jewish communities in the province, the largest being La Plata, Bahia Blanca, Mar del Plata, and Rivera, all affiliated with the Va'ad ha-Kehillot.
During the colonial period a few *Crypto Jews settled in Buenos Aires, mainly during the 16th and 17th centuries. There is evidence that the number of "Portuguese" (as many judaizers were identified at the time) of Jewish descent rose during the 18th century as Buenos Aires developed into an important administrative and commercial port city. However, there is no trace of Jews living openly as such during the time of the revolt
In 1909 there were approximately 25,000–30,000 Jews in Buenos Aires. In spite of some manifestations of antisemitism, especially during the repression against workers' strikes during the early years of the 20th century, and the "red-scare" pogrom – known in Argentina as La Semana Trágica – of January 1919, whose main targets were Russian Jews, immigration continued unabated, interrupted only during World War I.
After the war it was further enhanced by the quotas established in the United States starting in the early 1920s. By 1936 there were over 120,000 Jews in the capital, constituting over 5% of the total population. After 1933 a relatively large number of Jews from Central Europe established themselves in Buenos Aires. A few more did so after World War II from neighboring countries in South America. However, the Argentinian government closed Jewish immigration after the war, and only a small number of Jews entered after that. The city's Jewish population increased naturally and by internal migrations from provincial cities and from the ICA settlements.
Buenos Aires was a city of immigrants, cosmopolitan in character, and the Jewish population remained diversified as well. About 85% of the Jews were Ashkenazim, the vast majority from Eastern Europe and a minority from Central Europe. The other 15% were Sephardim from various areas in the Balkans, the Middle East, and North Africa. These Jews founded their new societies and communities along the lines of their places of origin. Ashkenazim were organized in *AMIA, the largest community organization in Argentina, while Sephardim organized themselves in four separate communities: Moroccan, Ladino-speaking (from Turkey and the Balkans), and two Arabic-speaking ones, the Jews from Damascus and the Jews from Aleppo. Each group had its own cemeteries, religious leadership, schools, and mutual-aid institutions. Most synagogues founded during the formative period by East Europeans and Sephardim were Orthodox, while those founded by the German Jews were either Conservative or Reform. During the 1950s CIRA became Conservative.
The founding of the Bet El community in 1963 and the Seminario Rabinico Latinoamericano in 1962 led to the spread of this movement not only in the city of Buenos Aires but also throughout Latin America.
The Reform movement established the Emanuel congregation in 1964. In addition, the Chabad movement has gained adherents, especially during the past generation. Nevertheless, Jewish identification is based more on national consciousness, and the influence of Israel and of Israeli political parties is greater.
This is made particularly evident by the important role of the OSA (Organización Sionista Argentina). Another central organization is DAIA, the representative body of Argentinian Jewry vis-à-vis the government and in the sphere of world Jewry.
Jewish education in the city was imparted along ideological and political lines as well as according to communal groupings. Most of the latter fall under the umbrella of the Va'ad ha-Ḥinnukh. Some of the day schools are among the best schools in the city, and at the end of the 1990s about 50% of Jewish children of primary school age and more than a third of secondary school age were reached by them. Many cultural, social, and sports organizations served local Jewry, especially Sociedad Hebraica Argentina, Hacoaj, and Maccabi ha-Ko'aḥ and Hebraica.
In earlier decades Buenos Aires was a major center of Yiddish journalism, to the point that in the 1940s three Yiddish dailies were published. In addition many monthly publications in Yiddish reflected the vigorous political and ideological splits in the community, ranging from Zionism of various schools to Bundism, socialism, communism, and anarchism. Buenos Aires was also a world center for the publication of books in Yiddish and a leading city for Yiddish theater. Subsequently, Spanish became the predominant and almost exclusive language for communal publications.
The Jewish population of Greater Buenos Aires peaked somewhere in the 1950s at approximately 250,000–260,000. From then on its numbers diminished, mainly because of emigration. The largest group immigrated to Israel, mostly for ideological reasons, during the military repression of 1976–83. Israel became a haven for Jews suspected of leftist or guerilla activism. Moreover, during the Argentine economic debacle that began in 2001, another current of emigration to Israel developed. In addition, Jews left Buenos Aires for other places in Latin America, the U.S., and Europe, mainly for professional and economic reasons, though, again during the repression, for political reasons as well. Thus, Buenos Aires, and Argentina as a whole, went from being a city of settlement to a city of exodus.
Jewish institutions were targeted during the 1990 by groups generally considered to be serving the cause of anti-Israel terrorism. Thus the Israeli embassy in Buenos Aires was bombed in 1992 with 29 people killed, and the premises of AMIA were razed in a major terrorist act in 1994 which killed 85 people. Ten years after the latter event the Argentine
In spite of the ups and downs of antisemitism, especially, but not only, during military repressions, Jews have played an important role in industry, commerce, the arts, literature, and journalism, and also in politics. During the administrations of Alfonsin (1984–90) and Menem (1990–2000), Jews were visible in all spheres of government.
