“When Puritan leader Oliver Cromwell died in 1558, it led to royalists restoring the monarchy in 1660, with King Charles II.
This began a new wave of persecution of non-conformists.”
The article skips over the wave of outright murder (not merely persecution) of non-conformists by Cromwell and his pals.

“The figures are even more horrific for Ireland, however: a total of 618,000 deaths from fighting and disease out of a total pre-war population of c. 1.5 million, or 41 per cent of the population. No figures are given for transportation to Barbados. Further confirmation of the above figures can be obtained from The Civil War 1642–1651 by Michael St John Parker (ISBN 0853726477).
A 41 per cent loss of population must surely represent one of the greatest tragedies of any people for any period of European history, not excluding the worst excesses of the twentieth century. We can take as an example the death rate from enemy action and war-related disease for Britain during the Second World War, which represents 0.6 per cent of the population.”
A previously unknown treatise by John Locke from the 1660s was recently discovered and published, on the question of whether Catholics ("Papists") should receive religious toleration. A later treatise by Locke is well-known in which he argues for toleration for Protestant dissenters but excludes Catholics and atheists.
