(CNN)Here's a look at what you need to know about the Oslo Accords, a series of agreements between Israel and the Palestinians signed in the 1990s.
Oslo I is formally known as the Declaration of Principles (DOP). The pact established a timetable for the Middle East peace process. It planned for an interim Palestinian government in Gaza and Jericho in the West Bank.
After the signing, Israeli Prime Minister Yitzhak Rabin and Palestinian leader Yasser Arafat shook hands.
The United States was not actively involved in the negotiations.
The meetings were carried out in secret over several months in 1992 and 1993.
Oslo II, officially called the Israeli-Palestinian Interim Agreement on the West Bank and Gaza, expanded on Oslo I. It included provisions for the complete withdrawal of Israeli troops from six West Bank cities and about 450 towns. Additionally, the pact set a timetable for elections for the Palestinian Legislative Council.
