Millions of Americans are expected to take to the streets this weekend as part of nationwide protests against US President Donald Trump and his government.
Coordinated by progressive organisation Indivisible, the No Kings protests planned for Saturday are expected to be the single biggest day of protest in US history.
Here's what to know about the rallies.
What are the protests for?
The organisers say this weekend's events will be protesting "authoritarian power grabs" by the Trump administration.
They say the president has broken several laws to carry out his policies and are calling on Americans to peacefully protest those actions.
"The president thinks his rule is absolute. But in America, we don't have kings and we won't back down against chaos, corruption, and cruelty," the No Kings website reads.
Where has Donald Trump been accused of making power grabs?
Since his second term began in January, the president has frequently been accused of breaking laws and seizing more power than is fair, or than his office entitles him to.
Here's a summary of some of the issues where Mr Trump has been accused by No Kings organisers of overreaching.
Elections
Republicans sparked an arms race over electorate maps in August when they began to redraw Texas' congressional districts.
Voters in those districts decide who will represent them in the US House of Representatives.
The new map Republicans proposed would have secured their party an additional five seats at the midterm elections next year.
That's a tactic known as gerrymandering, where districts are redrawn to include more voters in favour of one party to give a political advantage.
In response, politicians from other states have begun looking at how they might be able to redraw their election maps to give their parties an advantage.
While gerrymandering is legal in most states, the organisers of the No Kings protests have accused Republicans of "rigging maps to silence voters".
Free speech
In the wake of the assassination of right-wing influencer Charlie Kirk, the Trump administration vowed to execute a broad crackdown on liberal groups.
Without evidence, Vice-President JD Vance and White House deputy chief of staff Stephen Miller accused liberals of spreading "soulless and evil" propaganda that was encouraging violent crimes.
Mr Miller vowed to "used every resource we have" to "identify, disrupt, dismantle and destroy these networks".
Soon after the Federal Communications Commission strongarmed Disney into temporarily dropping its late-night talk show Jimmy Kimmel Live from air over comments the host made on Mr Kirk's death.
Critics accused the Trump administration of preparing a "campaign to destroy dissent" and eroding the values of free speech, which is a constitutionally-recognised right in the US.
Government shutdown
The US government has been shut down since October 1 as politicians duel over federal funding.
Democrats want an extension to tax credits that have subsidised health insurance for millions of Americans since the pandemic.
But Republicans refused to negotiate a compromise and allowed federal funding to lapse, putting millions of government workers on furlough and reducing the operation of most government services.
Mr Trump has also threatened to fire thousands of those workers during the shutdown, but those plans have so far been blocked by a judge.
On October 10, House Speaker Mike Johnson suggested the No Kings rallies were responsible for drawing the government shutdown out.
"The theory we have right now, they have a 'Hate America' rally that's scheduled for October 18th on the National Mall," he said.
"It's all the pro-Hamas wing and, you know, the Antifa people, they're all coming out, some of the House Democrats are selling tee-shirts for the event.
"It's being told to us that they won't be able to reopen the government until after that rally, because they can't face their rabid base."
The organisers of the No Kings protests shot back in a statement.
"Speaker Johnson is running out of excuses for keeping the government shut down," they said.
"Instead of reopening the government, preserving affordable healthcare, or lowering costs for working families, he's attacking millions of Americans who are peacefully coming together to say that America belongs to its people, not to kings."
Immigration
One of Mr Trump's key election promises was to crack down on illegal immigration.
Since returning to office in January, he has made deporting illegal immigrants a top priority for his administration, including by setting a quota for immigration agents to arrest 3,000 people a day.
That's led Immigration and Customs Enforcement (ICE) to significantly ramp up operations to locate and detain illegal immigrants in capital cities.
But while the government insists it is only targeting criminals and undocumented migrants, there have been numerous cases of citizens, permanent residents and tourists with valid visas being arrested and held in detention centres.
Kilmar Ábrego García was one of the more notorious cases of a wrongful arrest by ICE.
While Mr Ábrego García had illegally immigrated to the US in 2011, an immigration judge had granted him withholding of removal status, which allowed him to live and work legally in the US.
But under what the Trump administration claimed was an "administrative error", Mr Ábrego García was deported to an El Salvador prison in March without ever being charged with a crime or given a trial.
While he was returned to the US in June, he remains in custody, because the government has now charged him with unlawfully transporting illegal immigrants for financial gain.
Mr Ábrego García denies those charges.
Military
Mr Trump has deployed, or attempted to deploy, the National Guard in several cities that typically vote for Democratic politicians at elections.
Most recently, he deployed troops to the streets of Chicago, Illinois, and attempted to do the same for Portland, Oregon.
He claims the cities are in the grips of crime crises, which are impeding the abilities of federal agents to perform duties such as immigration performance.
That's despite FBI data showing crime is trending down in most major cities.
Whether the president has the authority to deploy the military on domestic soil in these cases is still up for debate, but a handful of judges have said it likely violates the 1878 Posse Comitatus Act.
That law generally prevents the military participating in domestic law enforcement and overriding the authority of state governments.
White House deputy chief of staff Stephen Miller found himself in hot water in early October after he incorrectly claimed the president had "plenary power" on the matter.
Plenary power refers to a government official having absolute control on a matter, according to Cornell Law School's Legal Information Institute.
That means a president with plenary power on a particular issue wouldn't need approval from other government bodies when making decisions.
The No Kings organisers pointed to the military deployments when arguing Mr Trump is "acting like a monarch".
"[He is] seizing control of DC, threatening other cities, and using federal forces against his own people," they wrote.
Third term
Mr Trump has toyed with the possibility of seeking a third term as president on several occasions since returning to office, even releasing Trump 2028 merchandise.
Under the 22nd Amendment of the US Constitution, presidents are limited to serving two terms.
But Mr Trump argues there are methods to circumvent that law.
He told NBC News one possible scenario could be having Vice-President JD Vance run for office and then pass the role to him.
How big are the protests expected to be?
Indivisible co-founder Ezra Levin believes the events will make for "the largest protest in modern American history".
More than 2,500 rallies are planned across the country, and significant turnout is expected at those taking place in major cities.
The first round of No Kings protests were estimated to have drawn about 5 million participants, and Mr Levin believes this weekend's will outstrip that number.
How have Republicans responded?
Republicans have attempted to get in front of the protests by branding them as anti-American.
Without providing evidence, House Speaker Mike Johnson suggested the protest participants are supportive of designated terror organisation Hamas, and are members of the far-left political action group Antifa.
Republican senator Roger Marshall said he doubts the protests will be peaceful.
"This will be a Soros paid-for protest for his professional protesters," he said.
"The agitators will show up. We'll have to get the National Guard out."
Indivisible co-executive director Leah Greenberg said the comments were "designed to intimidate, distract and divide", and the protests are intended to be peaceful.
Where does the No Kings name come from?
It's a reference to the foundation of the United States.
Before becoming an independent country, America was a collection of 13 British colonies along the east coast of the continent.
During the second half of the 18th century, many of the people living in the colonies became unhappy with king George III's rule.
While there was a variety of factors fuelling their discontentment, one of the main grievances was the belief that they were not represented in British parliament, despite paying heavy taxes.
Those people, known as Patriots, fought the War of Independence against England to eventually have America break away from the British crown and become the United States.
The Founding Fathers, who wrote up the constitution for the fledgling nation, envisioned a system where ultimate authority could not be given to one person (such as a king).
The No Kings organisers say the name is "the foundation our nation was built on".
"Because this country does not belong to kings, dictators, or tyrants. It belongs to We the People — the people who care, who show up, and the ones who fight for dignity, a life we can afford, and real opportunity."
