The idea for NEFFA came about in the summer of 1944, in a discussion over coffee after a square dance at the Boston
YWCA. The participants were Grace Palmer, director of the YWCA; Mary Gillette, head of the YWCA's physical education program; and
Ralph Page, the popular
New Hampshire caller who presided at the square dances. The series had been running for little more than a year, but was already drawing over two hundred people every week, most of them college students. As Ralph Page later recalled the conversation, they were discussing a recent attempt at a "New England Folk Festival" at the
Boston Garden which had left them unimpressed: "Mary said: 'Why don't we have a real folk festival?' and so the idea was born". Mary Gillette envisioned a festival where New England's many ethnic groups could share their song, dances, and crafts and present them to a wider audience, in a simple, honest, straightforward manner. Grace Palmer offered the facilities of the Boston YWCA. Philip Sharples, who in 1940 had founded the
Belmont Country Dance Group (one of the first square and contra dance series in the Boston area), joined with Mary Gillette and Ralph Page in calling local leaders to meet and talk it over. Many recreation agencies and ethnic groups sent representatives. From the start, the Festival Committee agreed to maintain an atmosphere of non-commercialism and high standards of performance and authenticity. The first festival took place on 28–29 October 1944 and attracted 200 attendees, mainly to watch performances of local ethnic dance performing groups. The NEFFA festival was founded in 1944, long before several more famous folk festivals, such as the
Philadelphia Folk Festival (1962) and the
Newport Folk Festival (1959). In recent decades, NEFFA has been influential as a model for dance and music festivals in New England, and nationally, including upstate New York's
Flurry Festival (founded 1988) and Maine's Down East Country Festival (founded 1991). Due to the
COVID-19 pandemic, the 2020, 2021 and 2022 festivals were held virtually. The festival has again been held in person beginning in 2023. == The festival program and performers ==
