Once, I was enslaved chained and bound but I escaped
Once, I had a dream and a speech of power but I got killed
Once, I couldn't breath and neck kneed but I was killed
Once, I could not catch a break but I protested
Once, I was power and couldn't be shaken but I still am
Once- Long Live Power

Doing so allows him to begin refuting this counterargument in the next paragraph.
It means "aunt on the mother's side".
