Learn Spanish (Latin America): La junta financiera se creó ayer. - The financial board was created yesterday.

While fue creada is grammatically correct, Spanish speakers strongly prefer using the "passive se" (se plus a third-person verb) when the person who performed the action isn't mentioned or isn't important. Saying se creó sounds much more natural for everyday situations.

I thought junta meant "meeting". How does it mean "board" here?

Junta is a flexible word! While it often means "meeting" in casual contexts, in business, organizational, or government settings, it translates to "board," "council," or "committee."

Why is there an accent mark on creó?

The accent marks the third-person singular preterite (past tense) of crear (to create). Without the accent, creo means "I believe" or "I create" (present tense). The accent tells you to put the stress on the final syllable, signaling a completed action in the past.

Since "was created" is in the past, could I use the imperfect tense and say se creaba?

No, because the word ayer (yesterday) gives us a specific, completed timeframe. The creation of the board was a single, finished event, which requires the preterite tense (creó). The imperfect (creaba) would imply an ongoing action, like "was being created."
