History News of the Week – Roman Construction Lessons

Building Lessons from the Romans New research is providing insights into how Roman harbours that are thousands of years old have withstood the ravages of time. Scientists from the US Department of Energy’s Lawrence Berkley National Lab used x-rays to study samples of Roman concrete – from an ancient pier and a breakwater, to learn more about the make-up of their mineral cements. Having previously found that crystals of aluminous tobermorite, a layered mineral, played a key role in strengthening the concrete as they grew in relict lime particles, the team’s latest research is piecing together how, when and where these crystals formed in the long history of the ancient structures. The research may ultimately influence modern construction techniques. It could lead to a wider adoption of concrete manufacturing processes with less environmental impact than those used for modern Portland cement, while the researchers also claim that an updated version of Roman concrete could be tested for applications such as seawalls and other ocean facing structures. The concrete could even be useful for safeguarding hazardous wastes. “At the ALS we map the mineral cement microstructures,” said Marie Jackson, a geology and geophysics research professor at the University of Utah who led the study. “We can identify the various minerals and the intriguingly complex sequences of crystallization at the micron scale.” “Contrary to the principles of modern cement-based concrete, the Romans created a rock-like concrete that thrives in open chemical exchange with seawater,” she continued. The research has been published in the journal American Mineralogist. Breakthrough in dating Viking fortress Archaeologists have made a breakthrough in dating the mysterious Viking fortress in Borgring, south of Copenhagen, which was first discovered in 2014. Ever since the fortress was first unearthed, a great deal of curiosity has surrounded the life, function and fate of the Viking structure. Researchers had speculated it dated to the tenth century, possibly to the reign of Harold Bluetooth (958 – 987), but it couldn’t be proven. In June of this year, archaeologists opened new trenches in a meadow next to the fortress, uncovering in situ some 2.5m beneath the surface a roughly 1m long piece of carved oak wood with drilled holes and several wooden pegs. A specialist in dendrochronological dating, Associate Professor Aoife Daly from the University of Copenhagen said the conserved part of the tree trunk was grown in the years 829-850 in the Danish area. “Since no splints have been preserved, it means that the tree has fallen at some point after year 966” Daly said in a press release. “The wood piece was found on top of a peat layer, and is fully preserved as it is completely water-logged. We now have a date of wood in the valley of Borgring, which corresponds to the dating from the other ring fortresses from Harold Bluetooth’s reign. With the dendrochronological dating, in conjunction with the traces of wear the piece has, it is likely that the piece ended as waste in the late 900s, possibly in the early 1000’s.” said research leader Jens Ulriksen. “In the coming week, the National Museum’s environmental archaeologists will take samples of wet depositions in the valley with the aim of uncovering how the layers have evolved from the earliest strata we have dated to the Bronze Age and over time,” said excavation leader Nanna Holm. The team hope that this will reveal exactly where the nearby river was when the fortress was built in the Viking Age. Funded by a grant from the A.P. Møller Foundation, the team included researchers from the Museum of South East Denmark and Aarhus University, as well as leading experts from the Environmental Archeology and Materials Research department at the Danish National Museum and the National Police Department’s Section for arson investigation. Poland seeks extradition of man accused of heading an SS unit Prosecutors in Poland are seeking the extradition of a 98-year-old man accused of being the former commander of an SS led unit that slaughtered civilians and burnt Polish villages to the ground during World War Two. Michael Karkoc has repeatedly denied the charges leveled against him, according to the Independent. Officials from the National Remembrance Institute in Warsaw accuse Karkoc of commanding a unit of Ukrainian nationalists responsible for mass killings in villages along Poland’s eastern border during World War II. The extradition request has been handed to the Polish embassy in Washington. According to the Independent, an inquiry by the Associated Press (AP) into Karkoc triggered the IPN investigation. The AP piece pointed out that Krakoc did not have a direct role in the atrocities, but was present and witness to them as a company leader. Whether Krakoc will be extradited will be governed by the EU – US extradition treaty. Krakoc is said to be suffering from Alzheimer’s disease, the Independent article states, raising questions over whether he’d be fit to stand trial. Earlier this year, his son Andriy Karkoc, fervently denied the charges leveled against his father.

Oswald Mosley – From Tory MP to Anti-Semitic Fascist

Who Was Oswald Mosley? “He struck me as being an earnest, rather humourless man; a bit of a bore, but in no way abhorrent; just rather dreary, like a Jehovah’s Witness, or one of those figures one meets in out-of-the-way places who produce a cyclostyled plan for world government which they have sent to Adlai Stevenson, Mrs Roosevelt and the late Duchess of Atholl.” Said Malcolm Muggeridge about Oswald Mosley in 1962, shortly after interviewing him for the BBC. Muggeridge’s description of the former leader of the British Union of Fascists makes him seem timid and harmless. Maybe by 1962 that was the case, but in the years leading up to the Second World War Oswald Mosley was a dangerous and influential voice in British politics. In 1932 Mosley united Britain’s fascist movements into the British Union of Fascists. The BUF gained widespread attention: MI5 claimed it had 50,000 members, including several prominent figures in society, and it won public support from the Daily Mail newspaper. The BUF was obsessively nationalistic to the point of authoritarianism. It was explicitly anti-Semitic and anti-Communist, while publicly supporting the policies and governments of Benito Mussolini and Adolf Hitler. The party, its members distinguished by their black shirt uniforms, was frequently involved in violent clashes. The most famous example came in 1936, when Blackshirts attempted to march through East London, an area with a high Jewish and Irish immigrant population. The violent confrontation that ensued has come to be known as the Battle of Cable Street. Mosley’s connections to the worst proponents of fascism was deep. His wedding to Diana Guiness took place in the home of Nazi propaganda minister Joseph Goebbels , and boasted Adolf Hitler as one of its few guests. Oswald Mosley and the Tory and Labour Parties Oswald Mosley was born in London in 1896. He served on the front lines of the First World War, as both a pilot and then as a soldier in the trenches on the Western Front. From 1916, when he was deemed unfit for front line duty due to an ankle injury, he took up a desk job for the rest of the war. In 1918 he became the youngest MP in the House of Commons, winning the Harrow seat for the Conservative Party. In 1924 he switched allegiances, joining the Labour Party. By 1927 he had become one of the leading figures in the party, viewed as a charismatic individual whose ideal of European Socialism meant many saw him as a future Labour prime minister. Mosley was influenced by the economic ideas of John Maynard Keynes, in particular government investing heavily to boost employment and secure the economy. In 1930 he proposed a radical programme to deal with Britain’s unemployment problem. Among other things it advocated a complete overhaul of the systems of government, with public funds being used to bolster the industrial sector. The proposals, which included the provision of old age pensions from the age of sixty, met massive resistance in the Labour government and Mosley’s radical ideas were ultimately blocked. Infuriated, he abandoned the Labour Party and founded the New Party in 1931. That year’s general election proved a disaster, with none of the New Party candidates being elected. Mosley Turns to Fascism and Antisemitism In 1932 Mosley met Benito Mussolini, who had been in power in Italy since the 1920s. Mosley was impressed by the Italian dictator’s government. Upon returning to England he dissolved the New Party, and replaced it with the British Union of Fascists. The new party quickly gained support, taking a fierce stand against Communism, and by October 1933 had its first elected official when Charles Bentinck Budd won a seat on Worthing Town Council. Soon however, the unsettling reality of the BUF’s ideology became apparent. BUF deputy leader William Joyce pledged to a public meeting in 1934 to rid British industry of foreigners “be they Hebrew or any other form of alien… Reclaim what is your own in the fullness of Fascist victory.” The anti-Semitic sentiment also saw the Blackshirts begin staging provocative marches in primarily Jewish populated areas, fostering tensions and igniting riots on British streets. Second World War and Mosley’s Arrest Throughout the 1930s the BUF remained a potent force in British politics, until the outbreak of World War Two. The declaration of war with Germany increasingly turned public opinion against the BUF, Mosley’s support of Hitler proving particularly alienating. On 23rd May, Mosley was arrested as part of new legislation allowing the Home Secretary to imprison without trial anyone believed to be a danger to national security. Soon other prominent BUF members were incarcerated, its publications banned, and the organisation quietly dissolved by 30th May 1940. ]]>
