Concerns Death Toll Maximum

Currently States 620000.000000

Petty's own upper estimate reached six hundred and twenty thousand, as much as two fifths of Ireland's pre-war population by some readings. Lenihan's own demographic scholarship, in his article "War and Population, 1649 to 52," argues this upper figure in particular overstates war-caused mortality, and no modern historian has produced a rival reconciled total that separates combat and massacre deaths from the era's simultaneous famine and plague.

Irish Confederate Wars, Wars & Conflicts

Standing Scholarly debate

Concerns Religious Dimension

Currently States The Confederation bound its members by the Oath of Association, a specifically religious oath to defend the public and free exercise of the Catholic religion alongside the king's prerogative, and Catholic clergy sat as full members of its General Assembly; the papal nuncio Rinuccini's presence and his demand for full Catholic religious establishment as a condition of peace, which split the Confederation from within, underscore how far religion structured the conflict on the Catholic side. O Siochru's constitutional study nonetheless stresses the Confederation was never a simple Catholic crusade: its moderate faction, led by Nicholas Plunkett, was consistently willing to trade religious toleration for political accommodation with the Protestant royalist Ormond, and dynastic loyalty to Charles I and Old English constitutional grievance ran alongside religious motive throughout.

Irshya (Envy), Vices

Standing Scholarly debate

Concerns Origin Period

Currently States Irshya, called issa in the Pali Abhidhamma where it is treated only as a secondary mental factor, becomes the fifth of the five poisons and is read within the five Buddha family scheme as the distortion of the wisdom that accomplishes all actions only in the later, more elaborate systematisation. John Powers's Introduction to Tibetan Buddhism (Snow Lion Publications, 2007) locates that five-poison, five-Buddha-family systematisation chiefly in Tibetan scholastic and tantric literature, later than the Pali material's earlier and more modest treatment of issa.

Concerns Historicity

Currently States Historicity debated

Lester L. Grabbe's Ancient Israel: What Do We Know and How Do We Know It? (2007) examines the patriarchal narratives against the archaeological and textual record for the second millennium BCE and finds no extra-biblical evidence for Isaac, and that the patriarchal narratives generally cannot be securely placed in any second-millennium setting. Judaism, Christianity and Islam nonetheless hold him to be a historical patriarch, the son of promise through whom Abraham's covenant passed to Jacob.

Isaac, Figures

Standing Scholarly debate

Concerns Mythic Association

Currently States The Genesis account of the Binding of Isaac, in which Abraham nearly sacrifices him at God's command before a ram is substituted, names him as the son involved, though Islamic tradition more commonly identifies the son as Ishmael.

The rabbinic and Christian tradition, following Genesis 22, names Isaac as the son bound for sacrifice at Moriah; the Quran does not name the son at all, and while a minority of early Muslim exegetes read the unnamed son as Isaac, the majority position, and the modern popular consensus among Muslims, holds it was Ishmael, reflecting a genuine, unresolved divergence in how the three Abrahamic traditions each claim their own founding covenant narrative for their own patriarch.

Concerns Manner of Death

Currently States Martyred

Not recorded in the biblical text itself, but later rabbinic and Christian tradition holds he was sawn in half on the order of the wicked king Manasseh, an account many scholars connect to the unexplained reference to prophets sawn in two in Hebrews 11:37.

Concerns Claimed Fulfillment

Currently States Both passages read as messianic prophecy fulfilled in Jesus of Nazareth.

Affirmed within Christian tradition since the New Testament itself. Jewish tradition reads the Immanuel sign as addressed to King Ahaz's eighth century BCE crisis and the Suffering Servant chiefly as a figure for Israel collectively; the disagreement is one of the oldest continuous arguments between the two traditions and shows no sign of resolving.

Isaiah's Messianic Prophecies, Prophecies

Standing Scholarly debate

Concerns Documented Response

Currently States Judaism's own documented reading of Isaiah 7:14, distinct from the Christian messianic reading already on this row. Read directly (Aish.com, Rabbi Dovid Rosenfeld): the Hebrew word is almah, "a young woman without reference to her virginity," not betulah, the Torah's own specific word for virgin, which Isaiah did not use; the sign names a contemporary woman whose son would be born imminently, in Rosenfeld's own words, this "couldn't possibly be referring to Mary who would not live for hundreds of years, and who would not bear a son till long after the battle Isaiah was referring to."

Standing Scholarly debate

Concerns Documented Response

Currently States Judaism's own documented reading of Isaiah 53's Suffering Servant. Read directly (Aish.com, Marshall Roth): the Servant is identified in the Servant Songs immediately preceding chapter 53, by Isaiah's own words, "You are My servant, O Israel" (Isaiah 41:8) and "You are My servant, Israel" (Isaiah 49:3), so, in Roth's own words, "there is no reason that the 'servant' in Isaiah 53 would suddenly switch and refer to someone other than the Jewish people."

Judaism, Christianity and Islam hold him to be a historical figure, the elder son of Abraham whom Islamic tradition names a forefather of the Arabs.

Ishvara Pranidhana (Devotion to the Divine), Virtues

Standing Scholarly debate

Concerns Origin Period

Currently States Dated by scholars anywhere from the second century BCE to as late as the fourth or fifth century CE, the same span debated for the Yoga Sutras as a whole: an early dating follows the tradition's own attribution to a single ancient sage, while a late dating, argued by scholars such as Philipp Maas, reads the surviving text as a composite assembled together with its own earliest commentary.

The Yoga Sutras' date is disputed among scholars, from a single ancient author around the second century BCE to a later compilation as late as the fourth or fifth century CE; the debate turns on whether the text and its earliest surviving commentary were composed together or centuries apart.

Concerns Attributed Author / Compiler

Currently States Traditionally attributed to Patanjali, the compiler of the Yoga Sutras; scholarship debates whether this is the same Patanjali credited with the Sanskrit grammatical treatise of that name.

Whether the Patanjali credited with the Yoga Sutras is the same figure credited with the Sanskrit grammatical treatise of that name, and whether the text as it stands is the work of one author or a later compilation, are both disputed.

Concerns Point in Dispute

Currently States How theistic the yoga of Patanjali really is, since his Ishvara, a special self untouched by affliction and karma and designated by the syllable Om, functions in surrender more as an object of contemplation than as a creator of the world. Edwin F. Bryant's The Yoga Sutras of Patanjali: A New Edition, Translation, and Commentary (North Point Press, 2009) surveys commentators who have argued the question for a long time.

Currently States 610

Islamic tradition places Muhammad's first reported revelation around 610 CE at Mount Hira near Mecca; the precise year rests on later biographical and hadith literature rather than a contemporary record, so 610 is used as a representative year for the start of this period.

Currently States 892

Turkic conversion to Islam under Samanid influence in Transoxiana was a gradual process spanning generations rather than one dated event; Satuq Bughra Khan's own personal conversion is conventionally placed around 934, decades into this window. 892 is used as a representative point at the opening of that process, not a settled year for any single conversion.

Currently States 1005

1005 is a representative point at the close of the Samanid to Karakhanid transition, during which Turkic conversion to Islam consolidated across Transoxiana following Satuq Bughra Khan's own conversion around 934; the process had no single closing date, and this end year marks where scholarship generally treats the conversion wave as complete rather than an event fixed on the calendar.
