Questions & Answers about El incidente sucedió ayer.

Why is it sucedió and not sucede or sucedía?

Because the sentence refers to a completed event in the past, so Spanish uses the preterite here.

• sucedió = it happened
• sucede = it happens / is happening
• sucedía = it was happening / used to happen

Since ayer tells you the incident took place at a specific finished time, sucedió is the most natural choice.
