"The Walking Dead" TV series features several significant groups and communities throughout its run, each with distinctive traits, leadership structures, and approaches to survival in a post-apocalyptic world overrun by zombies (referred to as "walkers" in the show). Here is a summary of the main groups and their interactions: 1. **Rick's Group**: Initially comprised of Atlanta survivors, this community undergoes various transformations. Led by former sheriff's deputy Rick Grimes, they seek refuge in places like Hershel's farm, the prison, Alexandria Safe-Zone, and eventually unite with other communities against common foes. 2. **The Greene Family Farm**: Hershel Greene's family maintains a relatively secluded and sheltered life on their farm until Rick's group arrives, bringing with them the harsh realities of the outside world. 3. **Woodbury**: Led by the Governor, Woodbury appears to be a safe and thriving community. However, the Governor's leadership is marked by brutality and paranoia, which ultimately leads to conflict with Rick’s group. 4. **The Prison**: After leaving the farm, Rick's group takes over a deserted prison, setting it up as a fortified shelter until it's destroyed during the conflict with the Governor. 5. **Terminus**: Introduced as a sanctuary for all, Terminus hides a gruesome secret. It’s inhabited by cannibalistic survivors who prey on those who arrive seeking refuge, leading to a deadly confrontation with Rick’s group. 6. **Alexandria Safe-Zone**: A walled-off community that manages to retain a sense of normalcy and security, Alexandria becomes the main base for Rick's group. Over time, they integrate and assume leadership roles. 7. **The Hilltop Colony**: An agricultural community led by Gregory and later Maggie Greene, the Hilltop works closely with Alexandria and eventually allies with them against common enemies. 8. **The Saviors**: A large, oppressive group led by Negan that extorts resources from other communities in exchange for protection against walkers. The conflict with the Saviors spans multiple seasons and significantly impacts all communities involved. 9. **The Kingdom**: A community with a quasi-medieval culture led by King Ezekiel. The Kingdom maintains a positive and hopeful attitude and partners with Alexandria and the Hilltop in the fight against the Saviors. 10. **The Scavengers**: Also known as the Junkyard Group, they are a mysterious community that lives in a junkyard. They initially align with Rick against the Saviors but later betray them. 11. **Oceanside**: A secluded community consisting mostly of women and children who have a hostile stance towards outsiders. They eventually become allies in the war against the Saviors. 12. **The Whisperers**: A group that disguises themselves with walker skin to move among the dead undetected. They pose a significant threat to the communities with their ruthless tactics and are led by Alpha and Beta. 13. **The Commonwealth**: An advanced network of communities that represent the most extensive and organized society seen in the series, with a strict class system and an array of resources. These groups interact in alliances, trade, enmities, and war, often shaped by the leaders' philosophies and the constant pressure of surviving in a world filled with walkers and hostile humans. Some of these interactions lead to the merging or dissolution of groups, and they reflect the series' ongoing exploration of themes such as leadership, morality, and civilization in a post-apocalyptic context. Their ongoing negotiations, battles, and strategic alliances are central to the plot and character development throughout "The Walking Dead."
