[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“How Africans Fought Slavery,”** on the hidden history of resistance to the Transatlantic Slave Trade among those targeted by it, with Richard Bell, professor of history at the University of Maryland, College Park. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/africans-fought-slavery](https://www.ticketleap.events/tickets/profsandpints/africans-fought-slavery) .] The Transatlantic Slave Trade was the largest forced migration in human history. In all, more than 12 million African men, women, and children were kidnapped and made to board European ships destined for the New World. Generally left out of our history books is the fact that African people fought the Transatlantic Slave Trade from the moment raiders approached their villages throughout every stage of the deadly Middle Passage. Join Profs and Pints fan favorite Richard Bell for a talk that turns the slave trade’s history inside out by examining the huge varieties of African resistance to this 400-year-long nightmare. He’ll discuss how African people fought capture through fortified villages, armed flight, and deception awareness. Their struggle to stay free involved rebellions inside African coastal forts, hundreds of shipboard mutinies, hunger strikes, and mass drownings. You’ll learn how African suicides and revolts, as well as the constant threat of captive rebellion, forced European traders to spend enormous sums on weaponry, guards, surveillance, and ship redesign. Such costs, historians now calculate, saved more than a million Africans from ever being trafficked across the Atlantic. Far from being helpless victims of an unstoppable system, African captives proved relentlessly defiant, leaving a record that reshapes our understanding of the trade and the roots of African American resistance.

[From the publisher's website](https://www.penguinrandomhouse.com/books/602335/maoism-by-julia-lovell/): For decades, the West has dismissed Maoism as an outdated historical and political phenomenon. Since the 1980s, China seems to have abandoned the utopian turmoil of Mao’s revolution in favour of authoritarian capitalism. But Mao and his ideas remain central to the People’s Republic and the legitimacy of its Communist government. With disagreements and conflicts between China and the West on the rise, the need to understand the political legacy of Mao is urgent and growing. The power and appeal of Maoism have extended far beyond China. Maoism was a crucial motor of the Cold War: it shaped the course of the Vietnam War (and the international youth rebellions that conflict triggered) and brought to power the murderous Khmer Rouge in Cambodia; it aided, and sometimes handed victory to, anti-colonial resistance movements in Africa; it inspired terrorism in Germany and Italy, and wars and insurgencies in Peru, India and Nepal, some of which are still with us today – more than forty years after the death of Mao. In this new history, Julia Lovell re-evaluates Maoism as both a Chinese and an international force, linking its evolution in China with its global legacy. It is a story that takes us from the tea plantations of north India to the sierras of the Andes, from Paris’s fifth arrondissement to the fields of Tanzania, from the rice paddies of Cambodia to the terraces of Brixton. Starting with the birth of Mao’s revolution in northwest China in the 1930s and concluding with its violent afterlives in South Asia and resurgence in the People’s Republic today, this is a landmark history of global Maoism. ***How to find us:*** We meet in the upstairs seating area at Zorba's in Dupont Circle.

Please join us for our first social gathering of 2026! This month, we'll be gathering at Busboys and Poets, Takoma Park. Located only a short walk from the Takoma Park metro, Busboys and Poets is a restaurant, bar, bookstore and community gathering place. First established in 2005, Busboys and Poets was founded by owner Andy Shallal [(@andyshallal)](https://twitter.com/andyshallal), an artist, activist, and restaurateur. After opening the flagship location at 14th and V Streets, NW DC, the neighboring residents, and the progressive community embraced Busboys and Poets, particularly activists opposed to the Iraq War. Busboys and Poets is now located in nine distinctive neighborhoods in the Washington D.C Metropolitan and Baltimore areas. Busboys and Poets is a cultural hub for artists, activists, writers, thinkers, and dreamers. This is a new venue for our meetups, so please note that all accessibility information was gathered over the phone and has not been verified in person as of yet. Service animals and companions are welcome!

Come volunteer with us refurbishing donated bicycles so that they can be used again by the community! This event is open to both new and existing volunteers. No mechanical experience is necessary. Note: The warehouse location is in the alley behind 1502. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Please be aware that volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver, while volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

Update: Hello friends! We're running into a scheduling conflict and pushing our social forward by 1 week. My sincere apologies for the last minute shift! We're starting off this year nice and easy with a Power BI DC User Group social! Please save the evening of January 15th in your calendars as we ring in the new year together with our trademark mix of camaraderie and general nerdiness. We're working on nailing down the specific location but will ensure that it is metro accessible. See you then!

Come the whole time or if you just spend 30 minutes. All are welcome. You are welcome and encouraged to bring your own coloring supplies but, if you don't have any, I will have plenty and am happy to share! (coloring books, colored pencils, and markers). Part of the mission of this group is to provide us an opportunity to check out AND SUPPORT local businesses. So, please don't bring any outside food/drinks and, while purchasing something isn't at all a REQUIREMENT to participate in the event, I do strongly encourage you to try something from the vendor :) I look forward to seeing and meeting you there! ***\*\*DISCLAIMER*\*\*** Photos may be taken during the event to be shared here on Meetup so feel free to let me know if you'd like to be excluded from them.
