On Ridgeway Hill in the County of Dorset, a mass burial was found with the remains of 54 males. These individuals had all been executed in a gruesome manner with their decapitated heads dumped together in a large pit. Interestingly enough all of the sharp blade wounds had been struck from the front, meaning these individuals had faced their enemy. Radiocarbon dating showed the bodies were from 890-1030 AD. Strontium isotopes found in the bones show these individuals were originally from Scandinavia.

The Anglo-Saxon Chronicle, which had been written around 890 AD, provides a year-by-year account of all the major happenings in Anlgo Saxon England. Aethelred the Unready had been king from 978-1016 AD - it is quite possible these bodies died during his reign. Initially the king had paid Viking raiders off with over 10,000 pounds to stop raiding their lands. Later they began hiring Norse mercenaries to fight off the invading Vikings - however these mercenaries would switch sides frequently and proved too risky.

The future French Revolutionary Jean-Paul Marat left home at the age of 16 to train in medicine and would eventually settle in Newcastle upon Tyne where he gained a reputation as being a highly efficient doctor who also had an interest in political writings. He moved back France 6 years later and his medical skills earned him the patronage of the aristocracy. He used his new found wealth to found a scientific laboratory where he began studies on fire, heat, light and electricity - he was even visited by Benjamin Franklin. Despite his new status and success, he began so spend a lot of time discussing and writing about social injustice.

As Louis XVI struggled to maintain power in the late 1780s by assembling the Estates-General for the first time in 175 years, Marat decided to end his research and medical profession to focus entirely on his passion for politics. He began writing on the topics of social, economic and religious reforms - this manifested itself in numerous vicious attacks on those he proclaimed were enemies of the people. His newspaper called for extreme violence against the upper class and government provoking statements such as five or six hundred heads cut off would have assured your repose, freedom and happiness. After reaching fame, He was elected to the National Convention in 1792 where he actively supported the death of the deposed King in a trial.

French revolutionists condemned King Louis XVI to death on 21. January 1793 by means of the guillotine at the Place de la Revolution in Paris (roughly where the Obelisk decorating the Place de la Concorde stands today). After a short but defiant speech he lost his head as the crowd rushed to the scaffold to dip hankerchiefs into his blood as momentos. An ornate gourd decorated with French Revolution themes was recently uncovered which had contained a blood soaked hankerchief dating to this time. The gourd was allegedly a gift to Napoleon Bonaparte who became First Consul of France in 1799 and Emperor in 1804. An anonymous Italian family was in its posession since possibly the late 1800s and came forward with the relic. It bears an inscription that Maximilien Bourdaloue on 21. January dipped his hankerchief in the blood of the king. Dried blood was scraped out and this is the same DNA we present in this DNA spotlight! The sample contains unsually high and rare markers for the Y-DNA haplogroup G2a.

Louis XVI's direct male line ancestor Henri IV was famous for enacting the Edict of Nantes which guaranteed religious liberties to Protestants ending 30 years of fighting between French Protestants and Catholics - he was assassinated in 1610 by a French Catholic zealot. The remains had been presumed lost in the chaos of the French Revolution after a mob of revolutionaries desecrated the graves of French kings in the royal chapel of Saint-Denis in Paris in 1793. However, the head was passed down over the centuries by secretive private collectors and positively identifed in 2010 with a radiocarbon date between 1450 and 1650. The features were consistent with the king's face including a dark mushroom-like lesion near the right nostrial, a healed facial stab wound and a pierced right earlobe. The hair color and moustache and beard on the mummified head fit the appearance of the king at the time of his death as well as matched his portraits. Furthermore cutting wounds were visible corresponding to the separation of the head from the body in 1793 and digital facial reconstruction of the skull matched the plaster mould of his face made just after his death in 1610. The DNA was then tested and compared to the blood from the gourd.
