This achievement can be unlocked towards the end of the game after completing the quest 'Together for Teer Fradee'. You need a specific outcome to this quest however, which has you successfully persuade every faction to join you when asked. You will of course need 'Friendly' reputation with all of the factions to be able to persuade them all to join you.

To see how to get good reputation with the Natives, Theleme and The Bridge Alliance, see the descriptions for "Carants", "Theleme's chosen" & "Favoured with the Bridge Alliance" respectively.

For good reputation with the Nauts and Coin Guard, you need to complete the factions quests associated with them.

For the Nauts, speak to the Admiral in New Serene who you can find at the Docks in-front of a giant globe that can be used to fast travel. She will give you a quest called 'The Naut's Secrets' which itself branches into 4 sub-quests; 'The Admiral's Secret Service', 'The Spy from Theleme', 'Sub Rosa' and 'The Enemy Within'. During these quests, you need to make choices that will give you positive reputation with the Nauts and the outcome of the overall quest needs to be that you discover the traitor and keep the Naut's secret, secret.

For the Coin Guard, speak to the Quarter Master in the Coin Guard barracks in New Serene to begin the series of quests and he will give you a quest, 'The Shadows of the Guard', that will break into 5 sub-quests; 'The Man With the Silver Coin', 'Champion of the Arena', 'Contraband', 'Dirty Traffic' and 'Egon's Face'. You will again need to make choices that will give you positive reputation with this faction and you will need to find out who 'Egon' really is and arrest him.

Once you have good reputation with all of these factions, you can then unlock this achievement at the conclusion of the main story quest 'Together for Teer Fradee', if you successfully persuade all factions to unite and join you.

Note that this achievements requirements also affect some of the endings, as you will need good reputation with all factions for an ending and need to not have good reputation with all factions for multiple other endings. So don't blindly get your reputation maxed out with them all without first making a backup save before doing, that can be used towards unlocking multiple endings in a single playthrough.
