Congregate and unite both bring people together, with a difference in what binds them. Congregate is for people to come together into a crowd in one place, of their own accord. Unite is to join people into one for a shared cause, so they act as one. Congregate gathers people in a place; unite binds them with a purpose.
Both gather people, but congregate only crowds them while unite binds them. Congregate, from Latin grex 'flock', is for people or animals to mass together in one place on their own — students in a courtyard, birds at dusk. Unite, from Latin unus 'one', joins people into a single body around a shared cause, with solidarity. Crowds congregate in the square; a cause unites them. One gathers in a place; the other joins for a purpose.
congregate
To congregate is for many people or animals to come together into a crowd in one place — usually of their own accord, and often for a shared purpose. From the Latin con- 'together' and grex, greg- 'flock' (the same root as gregarious and segregate). Students congregate in the courtyard; starlings congregate at dusk; protesters congregate in the square. It is intransitive — a crowd congregates on its own — and close to gather, but with a stronger sense of a mass assembling in one spot.
unite
To unite is for separate people, groups, or parts to come together and act as one — from the Latin unus, 'one'. A crisis unites a divided nation; scattered rebels unite behind a leader; two kingdoms unite under one crown. The word carries a charge of solidarity: those who unite often stay distinct yet stand together, as allied armies do when they unite against a common enemy. To unify is to make one cohesive whole; to unite is to join forces — to combine strength while keeping your own name.

Ask what holds the crowd together — place or purpose. Congregate simply masses people in one spot, of their own accord — a square filling with a murmuring crowd. Unite binds them with a shared cause — scattered figures joining hands into a ring. If people gather in one place on their own, that is congregate; if they are bound into one for a purpose, that is unite.

Congregate is intransitive and about people massing in a place on their own; unite is about people bound into one by a shared purpose. A crowd can congregate without uniting — gathered in one spot but not acting as one — and a scattered people can unite around a cause without congregating anywhere. Congregate needs a place; unite needs a purpose.
