Adams offers to meet the Orange Order for parade talks
The Sinn Fein president promised change as he delivered the key address of his party's annual ard fheis in Wexford.
And he said issues like an Irish language act, a bill of rights and the building of a peace centre at the Maze/ Long Kesh former prison site were not going away.
"These issues will be resolved. So too will issues of identity and contentious Orange parades," he said.
"While there may be obstacles, be sure of one thing - change will not be stopped.
"I am happy to meet with the Orange Order at any time to discuss these matters."
Dealing with contentious parades was one issue which former US diplomat Richard Haass failed to reach agreement on last year.
Mr Adams, Louth TD, said he wanted to see the Orange Order treating its Catholic neighbours with respect.
"I want to see it upholding law and order," he added.
"The Orange Order of Ireland is one of our national traditions.
"Orange is one of our country's national colours.
"And Sinn Fein wants all our traditions freed up from sectarianism from any quarter, to live together in peace and respect and with tolerance from everyone for everyone.
"The tide of history is with those who seek to build a peaceful and inclusive future. And Ireland, north and south, is changing."
