The list of others is shockingly long.  Not counting those who almost died during the Irish Republican Army Hunger Strike in the 1970s and 80s, many died in riots and street fighting.  They were protesting the British treatment of the Catholics in Northern Ireland, a situation that had gone on since before the "great famine."  Many in Northern Ireland still long to be part of the Irish free republic, outside of British rule.

When people go as far as starving themselves in protest, you know they mean business and believe in their cause.

Later, through the pressure brought by the organizing of both Catholic and Protestant women, they were able to gain some autonomy and peace in Home-rule.  
As with all revolts, the reasons are deeply economic and based in the bigotry of who were the "righteous and the chosen" people.  Sounds so tragically familiar to the conflicts worldwide, like American racial strife, the struggle between Israelis and Palestinians.  These situations are not truly over, I fear.
