President Donald Trump confirmed Friday that he is declaring a national emergency to secure funding for a wall at the US-Mexico border.

Before this, 59 national emergencies had been declared since the National Emergencies Act was signed in 1976, according to a list compiled by the Brennan Center for Justice.

Of those, 31 are still active. This is the 32nd, and it is Trump’s fourth while in office.

Take a look at some of the other active emergencies that are still in effect:

Blocking Iranian government property (November 14, 1979)

President Jimmy Carter declared a national emergency 10 days after Iranian students stormed the US Embassy in Tehran and took dozens of hostages. Carter ordered US banks to freeze all Iranian assets.

In November 1979, 66 Americans were taken hostage after supporters of Iran's Islamic Revolution took over the US Embassy in Tehran, Iran. All female and African-American hostages were freed, but President Carter could not secure the other 52 hostages' freedom. They were finally released after Ronald Reagan was sworn in as President 444 days later. Alain Mingam/Gamma-Rapho/Getty Images

Prohibiting Transactions with Terrorists Who Threaten to Disrupt the Middle East Peace Process (January 23, 1995)

Many of the national emergencies still in place regard economic sanctions.

President Bill Clinton signed this executive order to block the US holdings of what the government deemed to be terrorist organizations.

The emergency was signed a day after a suicide bombing near Netanya, Israel.

Regulation of the Anchorage and Movement of Vessels with Respect to Cuba (March 1, 1996)

Just minutes earlier, American Airlines Flight 11 had hit the north tower. The commercial planes were hijacked by terrorists in an attack orchestrated by al Qaeda leader Osama bin Laden. Another plane struck the Pentagon in Washington, and a fourth crashed into a field near Shanksville, Pennsylvania. A total of 2,977 people were killed. Kelly Guenther/The New York Times/Redux

Blocking Property of Certain Persons Undermining Democratic Processes or Institutions in Belarus (June 16, 2006)

These sanctions came after what Bush called “the fundamentally undemocratic March 2006 elections” in Belarus.

In 2006, security forces cracked down on protesters in the aftermath of the elections, fearing the replication of a Color Revolution.

Blocking Property of Certain Persons Contributing to the Conflict in Somalia (April 12, 2010)

President Barack Obama announced these sanctions in response to “the deterioration of the security situation and the persistence of violence in Somalia, and acts of piracy and armed robbery at sea off the coast of Somalia, which have repeatedly been the subject of United Nations Security Council resolutions.”

Blocking Property and Prohibiting Certain Transactions Related to Libya (February 25, 2011)

Obama froze the assets of Libyan leader Moammar Gadhafi, saying that Gadhafi, his government, and close associates “have taken extreme measures against the people of Libya, including by using weapons of war, mercenaries, and wanton violence against unarmed civilians.”

Gadhafi was killed later that year after being captured by rebel forces.

Blocking Property of Transnational Criminal Organizations (July 24, 2011)

These sanctions target criminal organizations that Obama said “have reached such scope and gravity that they threaten the stability of international political and economic systems.” Among the specific organizations mentioned in Obama’s executive order are the Yakuza in Japan and Los Zetas in Mexico.

Blocking Property of Persons Threatening the Peace, Security, or Stability of Yemen (May 16, 2012)

This executive order allows for sanctions to be imposed on anyone deemed to be threatening Yemen’s peace, security and stability by obstructing the country’s political transition.

Blocking Property of Certain Persons With Respect to South Sudan (April 3, 2014)

These sanctions are “aimed at persons who threaten the peace, stability, or security of South Sudan; commit human rights abuses against persons in South Sudan; or undermine democratic processes or institutions in South Sudan,” Obama said.

South Sudan gained its independence from Sudan in 2011, but the country has been mired in civil war since December 2013.

Blocking Property and Suspending Entry of Certain Persons Contributing to the Situation in Venezuela (March 8, 2015)

These sanctions were meant to address the human-rights crisis in Venezuela, specifically targeting individuals “involved in or responsible for the erosion of human rights guarantees, persecution of political opponents, curtailment of press freedoms, use of violence and human rights violations and abuses in response to antigovernment protests, and arbitrary arrest and detention of antigovernment protestors.”

Blocking Property of Certain Persons Contributing to the Situation in Burundi (November 22, 2015)

Obama signed this executive order to sanction those contributing to the unrest in the central African country of Burundi.

Burundi experienced months of violence after President Pierre Nkurunziza announced that he would run for a third term. The unrest left scores dead and caused more than 170,000 people to flee the country.
