The culture clash will continue in Season 4 of Julian Fellowes’ HBO period drama The Gilded Age, based on the turn-of-the-century time period in America that lasted between 1870 and 1900.

Some familiar faces have been promoted to series regulars since Season 3, and some new faces are joining the cast to play big-name historical characters, among other new roles for the large ensemble.

For everything we know about The Gilded Age Season 4, read on:

When will The Gilded Age Season 4 come out?

The show’s fourth season has wrapped production. Star Carrie Coon posted the news on her Instagram story.

How many episodes of The Gilded Age Season 4 will there be in total?

The Gilded Age’s fourth season will have a total of 8 episodes.

Will there be new characters in The Gilded Age Season 4?

Yes. Deadline broke the news in February that Taylor Trensch (Bat Boy: The Musical), James Scully (You), Dennis Haysbert (24), Maggie Kuntz (John Proctor is the Villain), Neal Huff (Mare of Easttown), and Tony Award-winner Bonnie Milligan (Search Party) would be joining the Season 4 cast in recurring roles.

Jim Gaffigan (Chappaquiddick), Dallas Roberts (Walk the Line), Elizabeth Marvel (Presumed Innocent), and Andrew Burnap (Snow White) have joined as guest stars.

Gaffigan will play Grover Cleveland, the 22nd President of the United States, who comes to New York to curry favor with the elite class. Roberts will portray Daniel Manning, a seasoned politician and Secretary of the Treasury under President Grover Cleveland. Marvel will play Nurse Virginia Saville, a kind nurse who works at the Neighborhood Settlement House in the Lower East Side. Burnap will portray Porter, a young gentleman of Society with an Ivy League education and money to invest in exciting new ventures.

Who else is coming back to The Gilded Age Season 4?

Jordan Donica, who plays Dr. William Kirkland, and Ashlie Atkinson, who portrays Mamie Fish, have been upped to series regulars for the upcoming fourth season. Kelley Curran, who plays Enid Winterton — formerly known as Turner when she served as Bertha’s (Carrie Coon) maid, has also been promoted to series regular.

Series regulars since Season 1 include Carrie Coon, Morgan Spector, Louisa Jacobson, Denee Benton, Cynthia Nixon, Christine Baranski, Harry Richardson, Blake Ritson, Taissa Farmiga, and Audra McDonald, who are all set to return.

What happened in Season 3 of The Gilded Age?

Donica’s character, Dr. Kirkland, proposed to Peggy Scott (Benton) in a happy, joyful moment at the end of Season 3. In contrast, George (Spector) and Bertha hit some rough waters in their marriage. This was largely due to Bertha’s rolling full steam ahead by forcing their daughter Gladys (Farmiga) into an arranged marriage. George felt he had no control and was angered by Bertha not wanting her daughter to have a shot at a love match.

It’s worth noting that George is upset on Gladys’s behalf; however, she married the Duke of Buckingham and ended up falling in love with him! Bertha’s sister Monica (Merritt Wever) came to town for the wedding, much to the former’s chagrin.

The Russells’ eldest, Larry Russell (Harry Richardson), courted Marian (Louisa Jacobson) all season, only to have what they built fall apart. After Larry and Marian became engaged, the former secretly spent time at a House of Ill Repute, aka a brothel, with Jack Trotter (Ben Ahlers). Instead of telling his beloved the truth about where he was, he lied and almost irrevocably broke their union.

Meanwhile, Larry and Jack sold the clock patent, allowing the latter to move out of the van Rhijn household and buy a nice home of his own with staff. People both upstairs and downstairs were stunned yet happy about his windfall. Thanks to Larry’s testimony, Marian gets a better understanding of his and Larry’s doings on that fateful night. As a result, Marian attempts to mend fences.

After the loss of a true love, Oscar’s being gay is exposed to his family, whether he was ready for them to know or not. Hey, this was the Gilded Age, after all. Neither his mother, Agnes ( Christine Baranksi), nor his aunt Ada (Cynthia Nixon) dared speak the words out loud, but there was an understanding. He did receive full support from his cousin Marian, who was not shaken by the revelation. It is, however, teased by the end of Season 3 that Oscar is seriously considering taking a wife, Turner.

By season’s end, Bertha was confronted with reality: her husband George was toying with the idea of divorce. You see, his life was forever changed after he was shot and nearly died. No one experiences such a tragic event and is the same person afterward. George seems to have become disinterested in playing a role in Bertha’s schemes, especially as they pertain to their children.

However, Bertha is a smart cookie and she has learned so much since Season 1. At the time when Season 3 was set, divorcees were branded social outcasts. So Bertha, while thinking ahead, helped influence a shift in social norms yet again. She persuaded Mrs. Astor (Donna Murphy), whose daughter Charlotte (Hannah Shealy) had recently uncoupled from her husband, to welcome divorced women like Charlotte and Aurora Fayne (Kelli O’Hara) to galas and high society social events.

Oh, and viewers have probably seen the last of Ward McAllister (Nathan Lane).

What is Season 4 of The Gilded Age about?

The official Season 4 logline reads, “Bertha Russell changed Society at a cost. Now, her family must reckon with the consequences as Agnes van Rhijn seizes an opportunity to regain her position. Meanwhile, Marian forges a new path for herself and Peggy works to be accepted by her future in-laws. In this new era, you must be careful what you wish for.”
