Congregate and consolidate both gather scattered things, with a difference in what and why. Congregate is for people to come together in a crowd, usually of their own accord. Consolidate is to combine scattered things into one stronger, firmer whole, or to make a position more secure. Congregate crowds people together; consolidate makes things one solid whole.
Both draw the scattered together, but one is a crowd forming and the other a strengthening. Congregate, from Latin gregare 'to collect into a flock' (as in a gregarious crowd), describes people gathering into a crowd of their own accord — worshippers, protesters, birds. Consolidate, from solidare 'to make solid', gathers loose things into one firm mass or secures a hold. People congregate in the square; a firm consolidates its offices into one. One is a crowd gathering by itself; the other a deliberate making-solid.
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.
consolidate
To consolidate is to make many into one solid — the Latin solidus sits unhidden in the middle of the word. Companies consolidate scattered offices; armies consolidate gains before advancing; the sleeping brain consolidates the day's learning into memory. The trade is always the same: a dozen small, loose holdings exchanged for a single firm one. What is consolidated stops being a collection and becomes a structure — and structures, unlike collections, do not blow away.

Ask whether a crowd forms or a whole is made solid. Congregate is people gathering into a crowd on their own — a square filling until it is packed shoulder to shoulder. Consolidate is scattered things made into one firm, secure whole — tiles locked into a slab that no longer skids. If people crowd together of their own accord, they congregate; if scattered things are drawn into one stronger whole, that is consolidate.

Congregate is almost always about people (or animals) gathering into a crowd, spontaneously and intransitively; consolidate is about making scattered things — debts, offices, power — into one firm, secure whole, deliberately. You congregate in a place; you consolidate things into one. The tell is a crowd forming by itself versus a whole made solid on purpose.
