Club play from pioneering Chicago DJs such as Hardy and Lil Louis, local dance music record shops such as Importes, State Street Records, Loop Records, Gramaphone Records and the popular Hot Mix 5 shows on radio station WBMX-FM helped popularize house music in Chicago. Later, visiting DJs & producers from Detroit fell into the genre. Trax Records and DJ International Records, Chicago labels with wider distribution, helped popularize house music inside and outside of Chicago. One 1986 house tune called "Move Your Body" by Marshall Jefferson, taken from the appropriately titled "The House Music Anthem" EP, became a big hit in Chicago and eventually worldwide. By 1986, UK labels were releasing house music by Chicago acts, and by 1987 house tracks by Chicago DJs and producers were appearing on and topping the UK music chart. By this time, house music released by Chicago-based labels was considered a must-play in clubs.

In the 1820s, Boston's population grew rapidly, and the city's ethnic composition changed dramatically with the first wave of European immigrants. Irish immigrants dominated the first wave of newcomers during this period, especially following the Irish Potato Famine; by 1850, about 35,000 Irish lived in Boston. In the latter half of the 19th century, the city saw increasing numbers of Irish, Germans, Lebanese, Syrians, French Canadians, and Russian and Polish Jews settled in the city. By the end of the 19th century, Boston's core neighborhoods had become enclaves of ethnically distinct immigrants—Italians inhabited the North End, Irish dominated South Boston and Charlestown, and Russian Jews lived in the West End. Irish and Italian immigrants brought with them Roman Catholicism. Currently, Catholics make up Boston's largest religious community, and since the early 20th century, the Irish have played a major role in Boston politics—prominent figures include the Kennedys, Tip O'Neill, and John F. Fitzgerald.

What religion did Irish and Italian immigrants bring with them to Boston?
Answer:
Roman Catholicism
