How does the civil war event work?

[Faeelin]

So I'm trying to get the following event to cause a civil war:

id = 900004
random = no
country = MEX
name = "Mexican Civil War Begins"
desc = "Troops ordered to fire on strikers in Sonora have refused to do so. Cardenas has crossed the border form America, and has promised to overthrow the Empire. It looks like we have a civil war of our own, now."
style = 2
picture = "scw"
date = { day = 17 month = april year = 1936 }
action_a = {
name = "We will prevail"
command = { type = province_keypoints which = 1968 value = 2 }
command = { type = province_keypoints which = 1967 value = 1 }
command = { type = province_keypoints which = 1981 value = 1 }
command = { type = province_keypoints which = 1966 value = 1 }
command = { type = dissent value = 25 }
command = { type = civil_war which = U44 }
}
}

I have U44 listed in the revolt file as having the same cores as Mexico. But nothing happens when the event fires. What am I doing wrong?

Don't use the civil war command. Use the independence command instead.

Don't use the civil war command. Use the independence command instead.

So I should just grand independence, seceding certain provinces, and putting the units there? Thanks.

Yes, it's better.
