In 1630, when Elizabeth was 45 the son of Robert Dudley, himself called Robert Dudley, began a rebellion against the catholic queen after she had had a child that had survived birth and been brought up a catholic and was the definite successor to Elizabeth and John. This rebellion had been planned for over 10 years and a reasonable militia of protestants. The rebellion began on Jun 12, 1630 in Rochester which had also been taken during Wyatt's rebellion under Mary I. The rebellion lasted for 2 years under the ill queen Elizabeth, leaving John IV of Portugal to be her consort for that time and deal with the rebellion which ultimately led to the Act created by Edward VII, the 'Act of Freedom'.
