The awards seek to acknowledge the inspirational work done by Irish individuals
The team behind the Yes Equality campaign have been named as the Community Group of the year at this year's People of the Year Awards.
Although the award is normally given to a smaller, local community group, the decision was taken to acknowledged that a grassroots campaign that had brought several groups together to initiate a process of change to the country as a whole.
Yes Equality put in months of campaigning to back a Yes vote in this year's same-sex marriage referendum. Through events, social media, phone calls, door-to-door visits and more, they proved instrumental in building support for the 34th Amendment.
The amendment was approved by referendum on May 22 by a margin of 62% to 38%, making it the first time any country had voted to legalise same-sex marriage by popular vote.
Crowds thronged the courtyard of Dublin Castle during the day, and after the result was announced thousands poured into the streets of Dublin to celebrate the momentous occasion.

Brendan McBride and consul general in San Francisco Philip Grant, who provided support to the families of students involved in July's tragedy in Berkeley, California, when an apartment balcony collapsed, killing six and seriously injuring several others.
