The Jewish avenger who killed an Ukrainian nationalist leader (THREAD)

This week, 33 years ago, Thomas Sankara, the revolutionary leader of Burkina Faso, was assassinated in a French-backed coup. He aspired to an egalitarian, feminist society, and an economy built on self-sufficiency, ecological regeneration, and independence from Western powers.

As debt crises mount across Africa, his ideas are more vital now than ever. I wrote about Sankara's legacy in these two pages from The Divide:

Today, Sankara's legacy is inspiring a new generation of revolutionary thinkers and activists across the continent and beyond. As Sankara himself put it, with uncanny prescience, “You can assassinate revolutionaries, but you cannot kill ideas”.

Sankara knew his assassination was coming. Speaking to African leaders at the OAU, he said "I would like this conference to clearly declare that we will not repay the debt; we must do it together, to avoid being assassinated individually..."

"...If Burkina Faso is the only one to refuse, I will not be here at the next conference."

THE BATTLE OF PRATAPGARH (10 Nov, 1659)

Chhatrapati Shivaji Maharaj's impeccable military genius and matchless courage humbled the Adil Shahi Sultanate.

The beginning of what was to come later for the M0ghuls from one of the most indefatigable defenders of Dharma!

Shivaji’s growing influence in Maval region, made him a threat to the Adil Shahi ruler of Bijapur who sought to restrain him. The man who was given the responsibility of this mission, was their commander, Afzal Khan. Afzal was a formidable warrior known for his ruthlessness.(1)

His strategy was to bring Shivaji out into the plains, where he held an advantage, compared to the rocky Deccan terrain. Afzal attacked the holy town of Pandharpur, and later demolished the temple of Bhavani at Tuljapur to instigate Shivaji in a bid to bring him out.(2)

Shivaji was angry but remained patient. Knowing that he could not defeat Bijapuri Sultanate in an open battle, Shivaji moved to Pratapgarh fort, located on rocky heights, surrounded by thick forests of Jawali.(3)

This set the pattern for future Maratha attacks, using guerrilla warfare against larger invading armies rendering them ineffective in unfavorable terrain.(4)

A thread on Wallelign Mekonnen’s 1969 essay “On the Question of Nationalities in Ethiopia” - which catalyzed the student movement that overthrew Ethiopia’s Solomonic dynasty in 1974 (Wallelign was killed in 1972 while hijacking an Ethiopian airlines plane) https://t.co/Ol0ElagLJq

Wallelign wrote that, while some call the question of nationalities "tribalism" - it is in fact "nationalism." Ethiopia is not one nation, he wrote, “it is made up of a dozen nationalities with their own languages, ways of dressing, social organization and territorial entity.”

Culture is nothing more than the superstructure of an economic basis that presupposes subjugation of the peasantry and proletariat. To be a “genuine Ethiopian” one has to speak Amharic and adhere to their culture. One must “wear an Amhara mask”- to use Frantz Fanon's terminology.

A common refute to the Neftegna system, whereby Abyssinian elites took lands from southern peoples, was that there are Amhara and Tigray masses in poverty. Another centred on representational politics. In reality, the feudal system oppressed all, but some groups more than others.

While Abyssinians are not dominant because of inherent imperialist tendencies, this is no excuse to perpetuate this situation. The only way forward is a state where every nationality is given equal opportunity to preserve and develop its language, culture and self-administration.

Why are loops called "loops"?

Before addressing the question in the title tweet, let me first back up to the origin of the term "quasigroup". The first use of the term was by Ruth Moufang in 1935 in her study of the multiplicative structure of the octonions.

Moufang defined "quasigroup" in a much narrower sense than we do now. The details are not part of this story, so I'll skip them. What she called quasigroups we now call Moufang loops in her honor.

The current definition of quasigroup - a set with binary op * s.t. for all a,b, the equations a*x=b, y*a=b have unique solutions x,y - is due to Hausmann & Ore (1937), in the same paper where they introduced the "other" meaning of "groupoid": a set with a binary operation

(3/15)

It was A.A. Albert (1943) who introduced the term "loop" for a quasigroup with identity element. In his words, "It will be very convenient to have a special name for such quasigroups..." (p.510)

In 1927, a young Spanish boy, aged 8, - who would become the 18th Duque de Alberquerque - sat in a cinema watching a newsreel of the Grand National.
In that moment, an impossible dream was born.
Born on the 15 December 1918, the boy - Beltran de Osorio y Diez de Rivera

- was so enchanted that he resolved one day win to the great race himself.
Aged 33, the Duke - having ridden in French steeplechases - made his Grand National debut in 1952, putting up ten pound overweight on his own eight-year-old Brown Jack lll (Pic), trained by Peter Cazalet.

The tall Spaniard fell at the sixth, sustaining cracked ribs and concussion

His second attempt came eleven years later aboard the Irish-bred Jonjo (named after its joint owners John O'Hagen and Joe Thompson).
Together the 44-year-old Duke and the 13-year-old Jonjo completed the

first circuit safely enough and were well up with the leaders when being unluckily brought down at the 21st.
In 1965 the Duke took a bad fall from Groomsman at Valentine's and was taken to Walton General Hospital with a broken leg

His ride in 1966 was on the doubtful stayer

L'Empereur who had to pulled up at the 26th

He was back again in 1973, pulling Nereo up at the Canal Turn. He finished 8th on the same horse the following year.

Yet another bad fall a week before the 1975 National resulted in yet another broken leg, ruling him out of the race,
