Let us see the decade changes as psychological cycles in the mirror of real events (which are inherited through fantasy impact of contemporary melodies, which can be carried by the weekly changes of Torah-reding melodies – and so we do find weekly or monthly differing fantasy (legendary) constellations which can be explaining the „horoscope effect” projected upon the stellar archetypal structures.
The 50 year long bank cycles /named by Schumpeter after Kondratyev) are changes in the amount of the sums of money which do have psychological impacts). The Biblical yovel (jubilee) years start at the end of the tenth years /17-18/ and tat he end of the Sixties (67-68).
They can be divided /traditionally, using Kabbalist names) four decades lasting 10-11-02 years.
In the Kabbalah (where the Higher power impacts us through Spheres of Feelings by generations of empathy evolution ) the First Decade is the Twenties (17-28 and 67-78 called the Brother /Son/ Years : the Twenties and Seventies of Innovations and Recovery (Source: Lloyd DeMause, psychohistory.com)
It is followed by the second era: the Thirties and Eighties /29-39/ /79- 89/ , which is called the Father Decade (new paternalist depressive repressive goals as a reaction to the innovative period.
It is followed by the Mother Decade (materialistis instinctive breakthroughs,/39-52 Forties and 89-02 Nineties/
It is followed by a meltdown-like double decade the Sister Years in the Zeros and Tens and the 50/60-s turnvers of Centuries and Half Centuries – Demands and Schizoid mayhem are characteristic. (They are doube in length because the century and half centur turnover has a deeper effect psychologically. This system does not want to claim that there are no random events independently of cycle types always – these are background unconscious group progresses and archetypical feelings that can mainly be used in teaching history and can barely be discerned in the present periods by contemporaries.)
We are able to discover in this „Decadology” system why we can see that there are recurrent nostalgies for the Tewnties in the Seventies in fashion trends and wh it is similar in the Eighties for the Thirties and in the Nineties for the Forties or in the Zeros/tens – turn of the Centuries – for the 50/0s the Half Century turnovers. These nostalgies van be seen in the length of hair of men and in the length of the skirts of women or in hat types..
Let us see the main Turnover years.
In history there are Liberal and Illiberal Cycles with 25 years main cycles. (DeMAuse) /And there the doble cycle of 50 years and that is doubled in 100 years. The Liberal Half Century is the most liberal in the years of 89/90 : there are Liberal/Materialist Revolutions at the Turnover of the paternalist Father-Decades into materialist Mother Decades. This si the end of the Eigthies and the Nineties.
Let us see them: 1588/89, 1688-89, 1789 and 1889 and 1989/90
/The Victory over Spain by England – the Anti-Catholic Glorious Revolution in England, the French Revolution and the Hungarian Independent-Army demonstrations – plus our presently paternalistic but maternally started liberal Soviet meltdown almost 25 years ago.
And what has preceded them 50 years earlier? (Again there was a turnover from Father Decade into Mother decade on the turnover of the Thirties into the Forties
1539: Henry the 8th cedes from the Pope.
1639: They begin to chase away the English King (Charles I)
1739. Wesley founding the liberalistic Methodist Church.
1839 : Blanqui the Socialist rebel leader is incarcerated.
1939 : Germans occupy Poland /These are also „materialistic breakthroughs./
And we can see the Turnover of the schizoid Sister Decade and the innovative restaurative Brother Decades in the Tens generally having serious conflicts.
1618: the Protestant English-leaning King is chased away in Tshechia and the War of 30 Years starts.
1718: The Spanish War of Inheritance restarts (as Louis XV is underage)
1818 : Napohas been conquered and his General /Bernadotte/ inherits the Swedish throne.
1918: the ending of the First World War.
Similarly decisive turning points happen at the beginning of the second Fifty Years at the end of the Sixties, (Sister Years) and beginning of the Brother Decade, the Seventies.
1668, : Louis XIV attacking Spanish Netherlands
1768 : The main responsable of the diminishing of American british taxes – which will lead to the Boston tea Party – , Lord Grafton becomes Prime Minister while anti-King rebel, Wilkes is inprisoned and 7 of his followers are murdered at a demonstration.
1867 The Appeasement between Hungary and Austria
1968 : Soviet Russian invasion in Tshechia. President De Gaulle chased away by demonstrations.
So we may see in this syste, how in history there are Liberal and Illiberal Cycles and how they are achanging.
According to this Date List it is imaginable that there will be coming a Liberal Turnover in the Twenties again (with the recurring innovative Brother Decades of the 20s /and 70s/ always starting at the ending of the chatotic Sister Decades- beginning in the years 17/18 and 67/68 again and again.
So in each week the Meshiah (called Jesus in most places) looks at his davidic ancestors and tries to help them with singing the same weekly Biblical melodies (As we have them today changing weekly). And the Rabbis tried to influence the contemporary Pharaon (to correct their character defects) by looking at the birth charts of important people in the year of their greatest stresses.
