President-elect Donald J. Trump’s inauguration is expected to draw thousands of protesters to Washington on Jan. 20. Several groups are planning rallies around the National Mall and near the parade route.

“In a normal election cycle, we’ll see four or five First Amendment applications,” said Michael Litterst, a spokesman for the National Park Service. This year, they’ve received at least 20 permit requests.

Protest organizers have used Facebook to share information about their plans and to recruit people to join them at the inauguration. Two of the largest protest events, Inaugurate the Resistance and #J20 Resist, have a combined total of about 15,000 Facebook users who have said they will attend.

An event organized by four students, Not My President, has about 20,000 Facebook users who have said they will attend, though the group has not secured a permit.

Supporters of Mr. Trump are planning their own rallies in addition to the official inauguration events. Two motorcycle groups, Let America Hear Us, Roar For Trump! and Bikers for Trump, have secured permits from the National Park Service and are coordinating rides to Washington from around the country.

The Women’s March on Washington, scheduled for Jan. 21, could be the largest inauguration-related demonstration in history even if it falls short of attracting the estimated 200,000 people who are expected to attend.

Hundreds of marches are expected to take place around the world on Saturday in coordination with the Women’s March on Washington.

Other protests are being planned elsewhere around the United States, often in association with groups demonstrating in Washington. Many have been organized by students, unions and socialist groups, including Socialist Alternative and Young Progressives Demanding Action.

The largest previous opposition demonstration at a presidential inauguration was in 1973, when an estimated 25,000 to 30,000 anti-war protesters disrupted President Richard M. Nixon’s second inaugural. Simultaneous demonstrations took place in cities around the world, including Paris, Stockholm and Tokyo, according to inauguration historian Jim Bendat.

President George W. Bush is the only other president known to have drawn large-scale protests at an inauguration. In 2001, protest organizers estimated at least 20,000 people demonstrated in opposition to the Supreme Court decision that resulted in Mr. Bush becoming president. "They carried big signs with foul language, hurled eggs at the motorcade, and screamed at the top of their lungs….While I couldn't make out their words, their middle fingers spoke loudly," Mr. Bush wrote in his 2011 memoir, “Decision Points.”

In 2005, opposition to the Iraq War drew more protesters to Washington for Mr. Bush’s second inauguration.
