Ireland has been fertile ground for reprehensible behavior by England for over 700 years. Ireland too, at times has committed acts of violence via a variety of Catholic and Protestant groups. The dead, wounded, and the mutilated are all that either side has gained. The hatred exists to this day, and while violence has been calmer of late, a great period of time must pass before memories fade and forgiveness is accepted for apologies offered.
Prior to the ships in this book becoming "Famine Ships" many plied another trade as "Slave Ships", it is true that there were structural changes made, but beyond a certain point conditions become inhuman, period. The Potato Blight is often the only, or the primary reason given for the mass immigration that devastated the island. The truth is always more complex, it is no different here.
While starvation was rampant the food that was available, food grown right there next to those that were starving was exported to England. The English Landowners often paid for the cost of passage on these ships where so many died. These ships did carry the victims of Famine like they had carried the victims of slavery before. Transportation was almost secondary, how can it be anything else when conditions are created that are deadly by definition. It was cheaper to pay for transit than keep people alive on their ancestral land. And if they left they no longer had any use for land, so it was bought and accumulated by the same individuals that often paid for its owner's permanent eviction.
Ireland today is experiencing the return of some of the descendants of those that made that terrifying crossing. As a nation it has become one of the most prosperous in Europe by many economic standards, but that is not enough. Tolerance is not good enough, nor are plans of peace that neither party believes in their heart to be fair. It would be pleasant to site examples of hatred hardened by centuries of pain that have been put aside and new beginnings made. Perhaps the newfound economic health will help the process, perhaps not.
I hope for those who live there, be they Catholic or Protestant, that a way is found in a comparatively brief span of time to pause, heal, for apologies to be made, and accepted.
