Corcaigh is based on the logo of Conradh na Gaeilge, the Gaelic League.

Corcaigh was first digitized in 1997 by Michael Everson and originally used the MacGaelic character set on the Macintosh platform, and ISO/IEC 8859-14 on the PC.

In 2010 Corcaigh version 3 was released in OpenType format, completely compliant with Unicode encoding and with an extended character set.
